I did of course, find out later that there were no production L-82 4-Speed cars sold to the public. I am assuming that the owner of the car I saw at the show either added the L-82 badges and valve covers or the manual transmission. Someone on this forum posted a scan of the letter they received from Chevrolet explaining that the option was canceled after they had ordered that combination. I wish I could find that thread. With that said, Chevrolet did build some. One of the cars used in the October 1979 Motor Trend road test was a L-82 4-Speed car. Is it possible that a pilot line car got into the hands of the public? I have seen that happen with other pre-production cars. One of the pilot line cars used in the 1979 press preview did survive the crusher... sort of: https://www.corvetteforum.com/forums...car-found.html

October 1979 Motor Trend- Options on Test car- L-82 4-Speed.

ZBD Suffix= L-82 Uncertain Usage

I have wondered if this is the car I saw back in 1989:

7.3 0-60 and 15.6 at 91 mph is what I come up with. Gear ratio might play a big part, I would imagine a 2.87 on a T350 is not a quick take off car so the 8.1 0-60 might be the result

I just confirmed through GMheritagecenter.com that the 1980 L-82 Auto had a 3.07 rear gear which confirms the slow times, 0-60 MPH, even with the automatic.

The 78/79 L-82 Autos had a 3.55 rear gear which confirms the 0-60 MPH time of 6.4-6.6 Seconds, making those 2 years, pretty impressive for the C3 L-82s! My 78 L-82 4 speed has a 3.70 rear gear and it is VERY fast today with its rebuilt/OEM L-82 Block (rods/crank etc) 355......

​​​​​​https://www.caranddriver.com/reviews...d-test-review/

FWIW-THIS car and Driver article (May 1 1980) on the 1980 C3 ^^^^^^^^^^^^mentions the L-82 4 speed was not offered or available.

Not sure why that other C&D article (???) previously posted mentioned any possibility of a 4 speed L-82 in 1980, a car which I specifically watched like a hawk back in 79/80 when I was a freshman in college or have ever seen an article that made that comment before.
