'70 Corvette LT1 Debut?

[olredalert]

-----Yup, Sam,,,,The January date is correct and I can give you first hand info on that as I bought an LT1 Vette vert brand new. It was ordered on spec by a dealer in Mass. and came in in late January of 1970. I think Ive mentioned the car before more than once. I was back in Mass that January to take my physical and head out to the front (so to speak). I would be lying if I said I wasnt depressed, and then I flunked that physical. Went back to my Moms to get ready to go back to Florida and saw all these new Corvettes getting unloaded off the truck. Ended up putting a deposit on that one that day! GMAC was my friend back in those days. The dealer was a holding yard of sorts for new Vettes that were ordered by other area dealers and I had quite a number to choose from but they were the first anywhere in New England for sure......Bill S

Thanks Bill. that the same 'vette that you used to tangle with a certain red mopar 'vert?

I'd be interested in what Marlin has to say wrt Don Yenko's knowledge of the LT1 as he made his 1st order of Deuces mid December 1969. I don't have Marlin's email at work so i can't email this link to him. Anyone .................thanks!

The LT-1 was ready to go before the end of '69 Corvette production, and I think I remember reading somewhere that emissions decals and engine suffixes were made available for '69 Corvettes before the '70 production run began.

Interestingly, the L-46 was available in '70 also, which means that this mixture of engines does seem theoretically possible for '69 production (same reciprocating assy.).

Based on this, were any '69 Corvettes produced with the LT-1?

To my knowledge, there is no documentation from Don Yenko and his thoughts on the 'vette LT1. The prevailing thought was that Yenko was simply following his previous model by putting the highest performing 'vette engine in a non-vette automobile - in '70 he chose the Nova to avoid the insurance scrutiny. I'm not convinced that Don did a lot of due diligence on the LT1, he saw 370HP in a 3180 lb car and knew he had a winner - so he submitted the combo for COPO approval. The kick was getting the 4.10 rear, as it was not an RPO in '70.

Just had a chance to read the whole post here. Rick is correct, the initial 'mule' of putting an LT1 into the Nova was available for the press day sometime in mid-late '69. The Mule Nova was actually a '69 version, and the press kit noted that 'neat Nova powered by an LT1 - not available to the public'. Perhaps Don keyed off of that, but most of us think what I typed above. The Mule was the COPO test version of Don's request.

-----I can give Y'all an unsubstantiated story from a Ft.Lauderdale postman that I knew back around 1975/6. He said he bought a new 69 Corvette (red with saddle vinyl) coupe that he said was an LT1 (delivered, new). I never saw it around back then. He bought it new at Slaton Chevrolet. He sold it in 72 or so and had no idea where it went, but he had a bunch of detail stories about small stuff that led me to believe that he wasnt a "bull$hit" artist.......Bill S
