L82 Performance Edition: 1976 Chevrolet Corvette
Last week I covered this 1976 Chevrolet Corvette and suggested that while it was uninspiring, in both color and lack of underhood oomph, I suggested that it was a product of its unfortunate times but it could serve as a reasonable entry point into Corvette world. Today’s Corvette find, also a ’76 variant, is powered by the one optional engine that was available so I thought it worthy of a comparison. This “Little Red Corvette” is located in Alameda, California and is available, here on eBay for a current, no reserve bid of $3,250 with seventeen bids tendered so far.
As late as 1972, Chevrolet still offered a solid-lifter, Holley carburetor fed, 350 CI small block V8 engine known as the LT-1. It was standard equipment in the Z28 Camaro and an option in the Corvette. As 1973 dawned, emission control standards became stricter and the LT-1 got the bum’s rush. Replacing it was RPO L82 (’73-’80) and it served, at first, in the same applications as its LT-1 predecessor. Though it was a Quadrajet/iron intake manifold arrangement, the L82 featured more robust forged internals, four-bolt mains, improved flow heads with a 9.0:1 compression ratio, and a more aggressive hydraulic lifter camshaft. Debuting with 245 net HP (the ’72 LT-1 mustered 255), the L82 was chugging out a middling 210 by ’76 but it was still a 30 HP improvement over the standard L48 version. The seller tells us that the “Original engine is tired, but still cranks up reliably” and surprisingly, is fed by an aged Holley fuel injection throttle body get-up. Unlike last week’s car, this ‘Vette utilizes an automatic transmission, a Turbo-Hydramatic 400, three-speed. This would be the last year for the big 400 auto. as diminished HP no longer required the services of such a robust box. The seller mentions that the transmission leaks, but works.
We’re looking at a twenty-four-year-old paint job (code 24 – Red) and it shows well, there’s no indication of fade or body seam separation but the front bumper reveals the results of having been kissed a couple of times. Unfortunately, there are no real comprehensive external images in the listing, so getting a complete look at this Chevy is a piece-it-together exercise. The optional cast aluminum wheels are a nice upgrade over the done-to-death standard Corvette Rally wheel but such items as bright door edge guards and “Chevrolet” lock cylinder decals detract from the ‘Vette vibe.
OK, the elephant in the room is the seats. The seller tells us, “Seats were partially reupholstered at that time with cloth inserts sewn over the original leather“. Yikes, my eyes! On a positive note, the carpet and dash pad were replaced at the same time as the exterior refinishing occurred, and both items present well. The interior, all-in-all, displays nicely it’s just those seats, wow! (And that steering wheel cover needs to go too.)
So, this ‘Vette has a lot more miles on its clock than the previously reviewed ’76 – this one is at the 123K mile mark, and the automatic gearbox is probably an enthusiast’s detraction. The L82 powerplant is preferred but this motor is, as the seller states, tired and it has the whole F.I. unit vs a carburetor matter to consider. But, the red finish is nice and more in keeping with what one would expect to find being worn by Chevrolet’s iconic two-seater. So, what’s your preference, a beige, standard engine, four-speed equipped model, or a red, higher performer – though tired, automatic-outfitted edition?

Comments
JOD- My “elephant” is the fan location and the ac belt. I think the fan blades should not be that exposed and the belt should not be that far over. I have not owned an L-82 for a long time, but I thought they had an aluminum intake manifold. Thanks.
Frank:
My recollection from ’73 was that an iron manifold was used because an aluminum one wouldn’t accommodate the new for ’73 EGR valve. Always sounded suspicious to me… Perhaps an aluminum one was employed later in the engine’s eight-year run – that I’m not sure of.

Derick goes to FLA and resurrects a 78 L82
fan shroud is a bit different but overall it looks a lot like this one
What the heck is going on under steering column???
Graphic equalizer?
What about the brass fittings and clear tubing??
Something to do with the fuel injection? I think it says Holley on the side of the box.
C3’s are incredibly easy to go from “meh” to “wow” with an inexpensive crate engine transplant.
No aluminum intake until I believe 1978. 86 L82 was 210 hp, with far better heads, 9.0:1 CR, more aggressive cam and four bolt main crank. They were decent performers. I was the assistant service manager at a very busy Chevy dealer them and drove numerous L82 stick cars that year. I believe this car had the tach replaced. That is not the correct redline for a true L82 that year. But my memory is going. This car has some 91 ? Looking mufflers on it.
Looks like an old Holley Projection TBI setup.
The ad mentions an older Holley TBI that needs work. Seller has lost the original Rochester carb.
Since its a real auction, someone will end up with a decent project, hope it doesn’t go too high.
Wrong hood. 1975 was the last hood with the air vents on the windshield end. I owned a new 1976 in my youth.
I could be wrong and I stand to be corrected, but it is my recollection that 1975 was the LAST year for the Turbo 400 transmission in the Corvette, and 1976 was the first year for the cheaper/less robust Turbo 350. If this ’76 does indeed have a 400, I would assume it was grafted in.
The GM Vehicle Information Kit for the ‘76 Vette states that the standard L48 engine (180 HP) utilized the Turbo-Hydramatic 350, while the L82 (210 HP) went with the 400. For ‘77 it was the T-350 only, regardless of power plant.
