I think the Turbo 400 came out in 67? Called the M40 if I remember right.

Yes it was one of the first. I didnt know they existed until I saw Leon's car. The 409/340 HP cars were P/G's or 4 speeds. The 400 HP 409's were all sticks. Leon can tell you about the 65 396 when you catch him at a Div. one race. It was that pale green color and a really good loooking car. The Vette he races today is the one I found for him back in the "stone age" that he raced as a stocker for several years. It was an original 427/390 HP automatic car painted in silver w/black interior.

You GM guys ought to be ashamed of yourselves.

TH 400 was actually introduced in 1964 in both the Buick and Cadillac lines.

1965 was indeed the first year for the TH 400 in a Chebbie.

Terry is correct.

Full size car only, optional behind the 396 big block.
