1971 Chevy Impala 'Vert Goes Mega-Donk With 383 Swap to Supercharged LT5 and 26s

This 1971 Chevy Impala ‘Vert that’s featured in the latest episode of the WhipAddict channel on YouTube was already a very cool donk build that lived its life and amped its reputationin Miami, Florida. But even though it was dressed up in brown paint with red inserts, as well as a crimson interior with matching top and undercarriage, it turns out this ride needed “just” a little bit more.

Or a lot, depending on what power its 383ci stroker engine was initially capable of. Well, it doesn’t matter anymore because the Impala traveled to Fayetteville, Georgia-based Kaotic Speed for a little transformation. Nothing “much,” just a switch from Amani to Forgiato 26-inch wheels, new brakes, a blacked-out frame instead of the red one, as well as a shortened and stronger rear end that was needed to handle the bigger wheels.

Oh, and some additional oomph. After all, the highlight of the upgrade project has to be the less-flashy but 800-horsepower capable new heart. The owner probably wanted his donk to be able to do everything, not just showing off its cool ride qualities. So, the folks over at Kaotic went for their first-ever supercharged Corvette LT5crate engine swap. More so, the mill also came with custom-engraved “Sliderridd” valve covers and a new transmission.

Most of the transformation is showcased during the first part of the video embedded below, and after a quick dyno run (shown at the 8:33 mark) it’s time for a decidedly fast ride-along to get a feel for the changes. Not everything was done just yet, as we noticed the new Dakota Analog dashboard wasn’t operating properly during the quick test drive, but that was sorted out after a brief stint inside the garage. Then, it’s ready to roar some more into the sunset (ok, off onto the boulevard behind the trees)!

The fifth-generation Chevrolet Impala were full-sizedautomobiles produced by Chevrolet for the 1971 through 1976 model years and was one of GM's top-selling models throughout the 1970s. Models included a sport coupe using a semi-fastback roofline shared with other B-body GM cars, custom coupe with the formal roofline from the Caprice, four-door sedan, four-door hardtop sport sedan, and a convertible, - each of which rode on a new 121.5-inch wheelbase and measured 217 inches overall. Station wagons rode on a longer 125-inch wheelbase.

History[edit]

Overview[edit]

The 1971 redesigned B-body would be the largest car ever offered by Chevrolet. All 1971 Chevrolet engines featured lower compression ratios to permit the use of regular leaded, low lead or unleaded gasoline of at least 91 Research octane per GM corporate mandate in anticipation of the catalytic converters planned for 1975 and later models which necessitated the use of unleaded fuel. A high-performance big block V8 was available in the form of the Turbo-Jet 454, which produced 365 hp in 1971, but power decreased as the years went along. The 1970s marked the impact of the 1973 energy crisis with gasoline prices doubling from 1973 through 1979 and industry car sales plummeted 20 percent between 1973 and 1974. For the first time in recent history, annual passenger car travel in the U.S. declined. The Impala's sales dropped to 176,376 units in 1975, the weakest since its introduction in 1958. An Econominder gauge package was offered for 1975 and 1976 models.[2]

1971[edit]

1971 Impala models offered the same body styles as previous years. Newly standard features included power front disc brakes, inside hood release, and a revised Astro-Ventilation system that utilized air distribution grills in the trunklid. The new body featured a double panel roof for improved rollover protection and flush exterior door handles - both features previously introduced on the 1970½ Camaro.

Engine offerings included the base 145-horsepower, 250 cubic-inch Turbo Thrift six-cylinder[3] (available only on the Impala four-door sedan as well as the lower-line Biscayne and Bel Air sedans) and 245-horsepower 350 cubic-inch Turbo Fire V-8 (standard on Impala Sport Sedan, Sport Coupe, Custom Coupe, convertible and Kingswood wagon, and optional on the sedan). Optional engines included the 255-horsepower 400 cubic-inch Turbo Fire V-8 (the standard Caprice and Kingswood Estate engine), 300-horsepower 400 cubic-inch Turbo Jet V8 and 365-horsepower 454 cubic-inch V-8. Early in the model year, all Impalas came standard with three-speed column shift manual transmissions and manual steering as standard equipment, with power steering and one of two automatic transmissions optional. During the first months of the model year, the three-speed Turbo-Hydramatic automatic transmission was optional with all engines while the two-speed Powerglide could be ordered with the 250 6 or 350 V-8s. At mid-year the Turbo-Hydramatic and variable-ratio power steering became standard equipment on all V-8 powered full-sized Chevrolets.

Station wagons featured a 'clamshell' design where the rear power-operated glass slid up into the roof as the tailgate (manually or with power assist), dropped below the load floor. The power tailgate, the first of its kind, ultimately supplanted the manual tailgate which required marked effort to lift from storage. This design was shared with other full-sized GM wagons from Pontiac, Oldsmobile and Buick. Subsequent generations reverted to the door-gate style for its full-size wagons. As expected, 1971 Impala production was well below 1970 totals due to the 67-day corporate wide strike at General Motors[4] that began in September, 1970 after initial 1971-model production began and would not end until November. Impala production ended up at 427,000 units including 2,300 with six-cylinder engines and 425,400 with V8 with other series production totals including Caprice, 91,300; Biscayne, 37,600; Bel Air, 20,000; and station wagons (all series), 91,300.

1972[edit]

1972 Chevrolet Impala Sport Sedan

The 1972 Impala introduced a lower height grille which extended below the bumper and revised taillights now set in the bumper. 1972 saw the last Impala convertible, the following year moving to the top-of-the-line Caprice Classic.[5] The Impala ragtop sold 6,456 units, placing fourth with just under 9% of the market, right behind the Corvette 6,508, ahead of the Mustang's 6,401.[6] Total Impala production for 1972 ended up at 597,500 units and other series totals included Caprice, 178,500; Biscayne (in its final year), 20,500; Bel Air, 41,900; and station wagons, 171,700.[7] The 250-cubic-inch six-cylinder engine was offered in Impala four-door sedans and sport coupes along with a three-speed manual transmission and manual steering at the very beginning of the model year with 1,500 Impala sixes built. After the short run of early-1972 six-cylinder Impalas were built in the fall of 1971, the six-cylinder engine and three-speed manual transmission were relegated to low-line Biscayne and Bel Air sedans. For most of the 1972 model year, all Impalas were V-8 powered and came standard with Turbo Hydramatic transmission, power steering and power front disc brakes. The standard Impala engine was now the 165-net 350-cubic-inch Turbo Fire V8 with optional engines including the 170-horsepower, 400-cubic-inch Turbo Fire V-8 (the base Caprice/Kingswood Estate engine), 240-horsepower, 400-cubic-inch Turbo Jet V-8 (rated at 215 horsepower on station wagons) or the 270-horsepower, 454-cubic-inch Turbo Jet V-8 – these were the engine offerings in 49 states; in California the only engines offered were the 165-horsepower 350 and 170-horsepower 400 Turbo Fire small-block V8s due to that state's much stricter emission regulations. The Astro Ventilation system was redesigned for 1972 with the vents relocated from the trunk lid to the doorjambs for improved reliability and efficiency over the troublesome 1971 system that was a major source of complaints from owners to Chevrolet and its dealers.

1973[edit]

1973 Impalas featured a larger, shock-absorbing front bumper due to new federal mandates which required 5-mile-per-hour (8.0 km/h) impact protection. The chassis was tweaked for better roadability, and new square taillights were mounted in the carry-over rear bumper. With the convertible now moved to the top-line Caprice Classic series, (continuing through 1975) Impalas were now all closed body styles for the first time in the nameplate's history and the station wagon known as the Kingswood since 1969 rejoined the Impala series. A 145-horsepower 350 cubic-inch Turbo Fire V-8 engine, Turbo Hydramatic transmission, variable ratio power steering and power front disc brakes were standard on all Impalas. Optional engines in all models included a 175-horsepower 350 Turbo Fire V8 with four-barrel carburetor and 245-horsepower 454 Turbo Jet V8; while the Impala Custom coupe, Sport Sedan and station wagons could be ordered with the 165-horsepower 400 Turbo Fire V8 that was standard on that year's Caprice Classic series. All engines were offered nationwide in 1973.

1974[edit]

For 1974, the rear bumper of Impalas and other full-sized Chevrolets incorporated shock absorbing cylinders to meet the upgraded bumper standards with new taillights above the bumper, separated by the license plate and fuel filler. The front end featured a new grille and headlight bezels, a new header panel, and a bumper with a drop down center section. The marker lights moved back up beside the headlamps.

1974 Impala Sport Coupe Spirit of America Limited edition

A limited-edition Spirit of America package was offered in 1974 on Sport Coupe models; primarily an appearance package, it featured white body paint, a white full vinyl top, white upholstery with red or blue trim, color-keyed seat belts and floormats, special wheel covers, optional white rally wheels, sports-styled dual remote outside rear view mirrors, a vinyl body side molding insert, and red pin-striping. Special fender and dashboard badges announced the package to passers-by and passengers.

This was the only year of the 1971–1976 models the Impala had a different front end design than the Caprice Classic, as other years used either a grille insert or previous year Caprice front to distinguish the two. The rooflines of the Impala coupes were revised. For 1974 the Custom Coupe was no longer a hardtop, with large fixed rear quarter glass and a thick B-pillar. The Sport Coupe, still a pillar-less hardtop, now used larger roll-down quarter glass like that of the 1971-73 Custom Coupe, and had a narrower, fastback style, flat back window similar to the 1966-68 Caprice coupes. The four-door sedan, four-door hardtop Sports Sedan and station wagons used carryover rooflines from 1973.

Engine offerings included the standard 145-horsepower 350 Turbo Jet V-8 on sedans and coupes, optional 150- and 180-horsepower 400 Turbo Fire V8s (the latter standard on Impala wagons), and 235-horsepower 454 Turbo Jet V8. In California, a 155-horsepower 350 V-8 with four-barrel carburetor was standard and the only engine options there were the 180-horsepower 400 and 454 V-8s.

1975[edit]

The 1975 Impala used a 1974 carried-over Caprice front end, with a grille insert and emblem change. The Caprice model carried a new front end with a swept back style header panel with recessed headlight buckets, a new hood, and new fenders. Also in 1975 upholstery, door panels and the dashboard were revised as were the radio and climate control graphics. Speedometers read up to 100 miles per hour (160 km/h), and added kilometers per hour. 1975 officially debuted a high-energy (HEI) electronic ignition system. Catalytic converters were also introduced as were several new options, including an Econominder gauge package, intermittent wipers, and a divided 50-50 bench seat (with a choice of sport cloth or vinyl trim).

A Landau appearance package was new for 1975. It featured an elk-grained landauvinyl roof (with a chrome band across the roof), a choice of special paint colors, sports-styled dual remote outside rearview mirrors, color-keyed wheel covers, a vinyl bodyside molding insert, and pin-striping. Inside were color-keyed seat belts and floormats; fender and dashboard emblems rounded out the package. (An identical trim package was also sold on the Caprice model.) Sport Coupe models were discontinued after the 1975 model year, leaving the redesigned Custom Coupe, with its wide "B" pillar and fixed rear window, the only 2-door Impala available in 1976. Engine offerings were similar to 1974 except that the 400 Turbo Fire V-8 was now only offered in four-barrel 180-horsepower form and the 454 Turbo Jet V-8 was no longer offered in California.

1976[edit]

The 1976 Impala used a previous year Caprice nose, with a new "egg crate" grille insert. The Impala had round headlamps while the Caprice used the new quad rectangular ones. Engine offerings were the same as 1975 in both 49-state and California offerings. This was the final year for the four-door hardtop sedan, the big block 454 V-8 now yielding 225 horsepower, and the station wagon clamshell tailgate. The pillarless Impala Sport Coupe faded out of the lineup; a formal-roof Custom Coupe was the only Impala two-door. After 1976, the four-door hardtop body style also would disappear. Measuring more than 222 inches overall on a 121.5-inch wheelbase, the Impala ranked as the last of truly big Chevys. Full-size cars made the most of their perimeter frame and full coil spring suspension to deliver a smooth ride. The interior had such luxuries as simulated rosewood vinyl trim on the instrument panel, steering wheel, and doors. Impalas rode steel-belted radial tires and carried an automatic transmission, power brakes, and variable-ratio power steering. The standard bench seat could be replaced by a 50/50 split front seat, as in 1975. The Landau model, for both Caprice and Impala, continued into 1976 as before. A lighted visor vanity mirror was new to the options list.

A lower-priced Impala "S" series, available only as a four-door sedan, was introduced this year for the United States market and functioned as a replacement for the Bel Air, which was dropped after the 1975 model year. The trim and standard features were similar to that of the departed Bel Air series (although this model used the same triple rear taillights as the regular Impala, unlike the twin-taillight setup of the Bel Air). The Impala "S" was sold primarily to fleet and government customers where luxury was not a concern, although the car was available for purchase by private customers who sought basic low-cost transportation with the convenience of a V-8 powered full-size automobile.

Impala 1971

Here's What Went Wrong With The 1971 Chevy Impala

The Chevrolet Impala is a full-sized automobile produced by Chevrolet between the model years of 1958-1985, 1994-1996, and 2000-2020. The Impala was the company's flagship passenger car and was amongst one of the highest-selling American-made cars in the United States. You might even want to read the real story behind the 1995 Chevy Impala SS, one year in the long time-span of the Impala production.

The class of the Impala is a full-size, with a FR layout, and the Impala currently has ten generations of models, spanning all the way to the current year. Although this is an extremely long-running car model, and being extremely popular over the years in terms of sales, we will go over why there are certain issues with the Impala.

Despite all models being fairly successful in the long run, there were some serious problems we found with the 1971 Chevy Impala. Add this to the list of everything you need to know about the Chevrolet Impala.

Let's see what went wrong with the 1971 Chevy Impala.

Overview

The 1971 redesigned B-body turned out to be the largest car ever produced by Chevrolet. All 1971 Chevrolet engines used lower compression ratios in order to adjust the fundamental specifications for  the combustion engine. This allowed the user to utilize leaded, low lead, or unleaded gasoline of at least 91 research octane per GM.

A high-performance V8 engine was available in the form of Turbo-Jet 454, producing 365 horsepower in 1971. However, power decreased as the years went along. The 1970s ended up marking the drastic impact of the 1973 energy crisis, showing how gasoline prices doubled from 1973-1979.

Industry car sales plummeted from 1973-1974 by a whopping 20%. The annual passenger car travel declined, the Impala sales dropped to the weakest since inception, and an Econominder gauge package was offered for the 1976-1979  model years.

1971 Model Year

The 1971 Impala models offered the same body style as in previous years. New features included power front disc brakes, a hood release on the inside, and a renovated Astro-Ventilation system utilizing grills in the trunk lid. The newer body featured a double panel roof for increased protection and flush exterior door handles.

Engine offerings for the 1971 year featured the 145 horsepower Turbo Thrift six-cylinder engine, along with the 245 horsepower 350 cubic-inch Turbo-Fire V8 engine.

Other engines that could be chosen for the 1971 model year was the 255 horsepower, 300 horsepower, and 365 horsepower. All of the Impalas came with a three-speed column shift, manual steering, and shift manual transmission.

The Downfall

Unfortunately for General Motors, the 1971 model didn't do too well. Maybe it is because the design was shared with other similar full-sized GM wagons like the Pontiac, Oldsmobile, and Buick. Or, it could be due to the 67-day corporate-wide strike at General Motors.

This strike began in September 1970, after the 1971-model production had already begun. The strike, unfortunately, would not end until November, causing a huge clog and backflow with the production of the 1971 model year Impalas.

The production for this year ended at 427,000 total units, with 2,300 including six-cylinder engines, 425,400 with V8 engines, and the rest being other series production choices. Reviews of the 1971 Chevy Impala in recent years have shown that owners frequently complain about the poor gas mileage, the lack of ability to get work done on the vehicle easily, and the wide stance making it difficult in city driving.

Conclusion

Despite the Chevy Impala being a reliable and stylish vehicle, this model year was unfortunately plagued by bad timing during the first release. The GM strike hindered the production of the 1971 year, causing financial strain for he company, a lack of production, and a lack of detail in terms of the cars, that made it off the conveyor belt.

1971 Dodge Polara Custom vs. Chevrolet Impala and Ford Galaxie 500 Dealer Promo Film

From the October 1970 Issue of Car and Driver

The Impala is Detroit's leading car, without a doubt. And when its format is altered noticeably it is only as the end result of a thought process that might not be obvious and therefore, deserves attention.

That is why in the year 1971—when all of the automobile world is touting the new Vega as the leader of an inexorable small-car trend—the news of the bigger Impala strikes a sobering blow. This size increase is even more significant when you under­stand that Chevrolet does not indiscriminately adjust the di­mensions of its bread-winner. For 1971, the Impala's wheelbase has been increased to 121.5 inches after a 12-year period at 119 inches. Overall length, on the other hand, has grown on a more or less yearly basis and the 0.8-inch increment this year is typi­cal of the annual rate for the last five years. But this silent ex­pansion accumulates to an astounding total size. The latest Impala is now a full foot-and-one-half longer and six inches wider than its counterpart of 15 years ago on a wheelbase that is greater by 6.5 inches. In fact, a Cadillac of that vintage was actually shorter than today's Impala by two full inches.

Obviously, this growth business can't go on or we'll be driving Fruehauf-size sedans by the turn of the century. Under close scrutiny, the Impala seems to have grown less by plan than by lack of restraint, like the pot belly that comes with age. And its cautious, evolutionary styling further suggests a car that con­tinues with very little attention to purpose or concept. Yet this car, which seems never to change significantly, is altogether different than the Impala of a year ago—at a fantastic expense in both engineering and tooling. Altogether different—new body and new chassis—to do the same job in the same way. The en­gineers can defend their work. They will haul forth recorder tapes to show that the new Impala rides perceptibly better to an electronic sensor, has a lower interior noise level and perhaps a marginal improvement in handling. But, blindfolded, not one man in ten could tell the difference. Another round of improve­ment with no progress. For the really bothersome situations, like parking and edging through urban congestion, there has been not even an attempt at relief. Interior dimensions have been juggled rear leg room is up significantly but hip room is down and the yawning increase in shoulder space doesn't mean a damn thing since the old model had plenty.

All of this should not be construed as a condemnation of Chevrolet's largest seller. It does its job, as seen by General Motors and by the industry, with unprecedented competence and it is typical of its Ford and Chrysler competition. At the same time, the all-new Impala puts the Detroit small car flourish into perspective—more like a ripple than a wave.
