I don't believe LT1 had aluminum heads until 94 or so. I believe the LT1 had a forged crank and L46 cast, but I may be wrong on that. I feel that GM had no damn right to re-use RPO engine codes at all. But at least they could have retired LT1, LS5-6-7...

Two totally different engines, LT-1 and LT1. It is the LT-1 that was available in C3's.

Our Dana Chevrolet 1968 Corvette, in 1968 left the dealership new with solid lifters and cam and a Holley, etc. and Dealership Mods!
The way Massachsetts RMVs work, I could see the registration getting screwed up in any state with a state "worker"...

And the 68 with solid cam sounds like a L79 package

My understanding is that the LT1 was planned/considered for 1969 but delayed and not introduced until the 1970 model year.

Thoughts? Input?

Thanks!
There was a mis-print in the owners' manual showing a listing for LT-1....They never made it. This I believe is where this MYTH started..The Closest You could get to it was the L-46...which is a hydraulic 350/350, ostensibly. Many L-46's dyno out at 380 + hp at the crank....plus you could get A/C...which you couldn't until 72 in a LT-1....which by that time were making some 250HP.....LESS than the base engine in 1969.

"ask a man who owns one" lol Hey Dmaxx...got you beat....1969, L-46, Two top, Side Exhaust ,M-21.....36k miles....$3000...of course I bought it in early 1978! LOL

I just read the article in the Car Life magazine and I was trying to get my hands on a copy of the Bizzoco book but it is quite expensive. There has been mention of Mule cars which I assume are test cars. Does anyone have any further information on how these cars might be identified? The numbers on the block have been XXXXX'd out and as far as I can tell that would be the only difference, aside from the engine, that might help identify the car.
If this is the one in Michigan, I have seen the car and inspected it. Despite the documentation - which is written in the early 80s I believe - too much of the car has been rebuilt or restored to verify anything. The owner would have been better off leaving it alone or documenting work with copious beforehand pictures.

If it is another car, then two share a similar story.
