My 5,000-lb '69 Cadillac can run the same 1/4 mile time as that '77 Corvette, or even edge it out!
the 16.6 quarter mile time on the 77 was most definitely NOT the L82 motor that is in this car. L82's ran low 15's all day and 0-60 in 6.6 or so.

Not sure why you'd need to change the carb, they came with q-jets that were good up to 800 cfm. Yes you'd most certainly would want to change the cam, although that was probably a "hot" cam for that year.

The pistons....I would think you could reuse, even if they are dished, but I would think the heads would be a better alternative....those heads are probably the famous 882 paper weight castings. Not much good on power. The intake I'd also replace....and yes a good exhaust is needed there too....

So pretty much the top half of the engine, cam and exhaust....

But OTOH since the engine has a lower c.r., the thought of a turbo or even a centrifugal s/c has crossed my mind..... I'm thinking as long as you don't detonate it, it should be ok.

the car has been sitting for 30 years so either way the engine I am sure would need a rebuild.

I agree. I don't believe that it's 33 year old gas. I think this story may have been a bit "Embellished"

And low 15s is many car lengths behind a 14.17.

I did find specs for a '79 Corvette with the L82 engine:
0-60 mph... 7.3 seconds; 1/4 mile... 15.7 seconds.

But were they "babied highway miles"? You have to be careful here - make sure you understand exactly what kind of 13 miles that we are talking about.

Yeah, I remember that. Some of the "fashions" and what was "in" back then was hilarious!

IO never said low 15's and 14.2 was not car lengths apart did I? I just pointed to the fact you had incorrect information


Road & Track took a 1978 L82 to 60 mph (97 km/h) in just 6.6 seconds, 127 mph (204 km/h) flat out, and covered the quarter-mile in 15.3 seconds @ 95 mph.

I know he didn't say it... I said it (because it's true). What was the "incorrect" info I posted? The times for the '79 'Vette I listed?

A top-of-the-line (powerwise) Corvette running 15.3 seconds was good in 1978 but poor by 1960s standards because the most powerful Corvettes in the '60s were running in the 13s @ 105+ mph.
That is why I made my original statement... too bad it wasn't a '68 Corvette with 13 miles instead of a '78. Don't know why you are defending a '78 Corvette so strongly! Every (classic) car fan knows that the older ones were more powerful and faster (thus more desirable).
