L48 or L82 vette???

I have bought a super nice 1980 vette but i'm not sure how to tell if it is an L48 or an L82. On the 77 back cars it told on the console. I'm not sure where to look on this car. Is there something on the engine that would give it away or do I need to have the trim# run. How do I find out?? There has to be something simple. Any help or suggestions would be greatly appreciated.

Doc here,

Find the block casting number and post it here, I can tell you what it is..

1980 also had an LG 4 , 305 Option, Non option for California bound vehicles , smog issues....so it could be anyone of the 3..

Gong by the VIN is fine , unless the engine was changed along it lifetime..then it could be different..Casting numbers are the best Identifier.

I thought that the vettes from 1978 through 1980 that had L82 engines were distinguished by the letter and numbers on the outside of the hood. Simply read "L 82" on each side of the hood hump. If the unit is the correct color and hasn't been fooled with I would think that the hood would be your first bet on whether or not it is an L 82. Just my thoughts.

4sp or auto

In 1980 you could not get a 4 speed with the L-82. (not sure about CA)If yours is a auto then it's a bet that it's a L48. I had a 1980 4 speed car with the L48. The L-82 cars had the L-82 emblem on the fender not hood. I'm not sure but I bet the red line on the tach would be 5600 rpm or so.
My L48 had tin valve covers and black air cleaner lid. L82 may have aluminum covers and possible chrome lid. You should have a mild lopey idle also if it's a factory L82. My camshaft went flat when it had 20000 miles so I put a 350hp327 cam in it. It sounded very sweet. Some day I would like to get another one. I loved the style of the body.

all of 165 or 175 hp. I wonder how many people have bought those cars thinking they at least had a 350.

Doc here,

Another Bit of trivia about the 1980 Vette..

It was the ONLY year that came STANDARD with a Dana, limited Slip, posi..

It was after that year, the bean counters at General Mystery decided that it was far too Costly to offer as a standard equipment Item at Corvette's Current base price.

After that, You could opt one..but you'd pay for it..

Doc here,

Well, as I understand it, you had to OPT for it anywhere else but California..(so they had to have at least a clue.)

In California, It was the only Engine available for sale...AND General Mystery Gave a Whopping $50 Rebate for getting stuck with it..

Somehow I get the feeling, that by the beginning of the 1981 year run, The Engineers were walking away from (at least the CA models) Shaking their heads saying.." Well, We Ain't EVER gonna do that again.."

I've worked on several of these things (Ca 80's) AND I find no two alike..like they were inventing on each build order..

Also, 1980 was the first year for Computer controlled Disaster..(The CCC Computer..Very Basic, but fraught with gremlins..)

If you need to find it...It's in the Battery box in front of the battery..

Hummm, let's see..Corrosion, Heat, and passenger compartment dirt..That will make that puppy last a long time..What were they thinking..?

Doc
