Re: 1966 GM 'Heavy-Weights'
 

what transmission did these cars use.
I think the Turbo 400 came out in 67? Called the M40 if I remember right.

Re: 1966 GM 'Heavy-Weights'
 

Turbo 400 came out in 1966.

Re: 1966 GM 'Heavy-Weights'
 

Turbo 350. Mine is a 69.

Re: 1966 GM 'Heavy-Weights'
 

The Turbo 400 came out in 1965......My friend Leon Marainnian (S/S Vette racer today) had a 65 396/325 HP SS Impala with a 400 Turbo he raced when new.in stock at 75&80 in Md........first one I ever saw. Small block cars still had the P/G.

Re: 1966 GM 'Heavy-Weights'
 

Must of been late 65 with 396 first half of the year was still the 409 and I have never hear of it coming with turbo 400.

Re: 1966 GM 'Heavy-Weights'
 

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.

Re: 1966 GM 'Heavy-Weights'
 

Will have to ask him next season at a race. Off the big car thing but I wonder what happen to his brother 69 camaro S/Stock

Re: 1966 GM 'Heavy-Weights'
 

Eddie sold the Camaro (dont know who bought it) Then went Comp. racing with a R.E.D. with a Lingenfelter engine. Then he got married and built a home and quit racing.

Re: 1966 GM 'Heavy-Weights'
 

What was Blakenship's car??? In B/S I believe.

Re: 1966 GM 'Heavy-Weights'
 

66 427/425 HP Chevy Biscayne.

Re: 1966 GM 'Heavy-Weights'
 

No problem......The Dragster was a big block that ran in A/ED and I think he won Englishtown with it many moons ago. Dont remember the exact year.

Re: 1966 GM 'Heavy-Weights'
 

Anyone here care to take a guess who these two fellows are working on this 1966 427 Biscayne.

Re: 1966 GM 'Heavy-Weights'
 

He would be correct...Bill Mitchell of World Products fame and Joel Rosen of Motion Performance.

Re: 1966 GM 'Heavy-Weights'
 

Here's another 66 427 Biscayne from the Sheehan Brothers...perhaps they could tell some stories about this car.

Re: 1966 GM 'Heavy-Weights'
 

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.

Re: 1966 GM 'Heavy-Weights'
 

That's my fathers 66 factory 427/425 Biscayne. This was the first modified Biscayne by Motion Performance. He raced it at National & West Hampton from 66 to 68. He drove it to work one day to Brooklyn N.Y. and it was stolen. I'm building a replica of the car and should have it out this summer.
