L82 Engine
I am in the process of buying a 1976 L82, the VIV# is correct but the engine number is missing. I can check the casting # to find out if it is the correct year, But is there any visual differences in the engines. How did the L82 generate more power, did it have different heads where I could check the casting numberes?
If I cannot confirm that it is an L82 I will not want to buy it.

The L-82 came with aluminum valve covers & intake. The head # is the same for both motors...........

Thanks for the input SEVNT6, but the description in the add says an Edelbrock intake manifold is fitted, the engine photo I have shows alumimium valve covers, I do not know if they are original.

I found L-82 covers at a swap meet for my L-48 & then had them chrome plated, but they look like this............

It looks similar, but I can only see the drivers side valve cover and it has a breather on the front and an oil filler cap at the back. Reverse as shown in your picture if you imagine the decal is the oil filler.
If I buy it can you clean it up to look like your engine bay

How long did they keep the beefier parts on the L82's? right to the end?

A couple of things that may help.
1. All automatic 1976 L82 vette's left the factory with a Turbo 400 transmission. An easy way to tell if you only have pictures to go by is that the TH400 does not have a kickdown cable.
Tranny code = CZ
2. Cylinder head casting# = 333882 for all '76 vettes.
3. 1976 L82 Carburetor numbers:
4 speed: 17056211
Auto: 17056210
Auto with A/C: 17056506
4. 1976 L82 Distributor numbers:
4 speed: 1103200
Automatic: 1112979

Couple of questions:
Is the motor redone?
How much is the asking price?
Are you looking to build an NCRS Vette?
If the answers to 1 and 3 are no, and if you are paying a substantial amount, I would forget it and buy a nice crate motor.
76 L82s sucked as far as horsepower and Torque!!!
