Tranny 350

[septer]

Just a qusetion... Any turbo 350 tranny should bolt up to any chevy 350 correct?

I don't know what years you are talking about here, but I seem to recall there being a bolt pattern difference on some. In other words, the TH350 trans was also used behind Olds, Pontiac, Buick and Chevy. But as I recall the bell housing from say an Olds, was different than the one used behind a small block Chevy...or perhaps Olds and Chevy where the same, but Buick and Pontiac where different, I cant recall which way it went, but I seem to remember one or the other having a dip in the top center(perhaps Olds and Buick?), while the others went around at the top(Chevy and Pontiac?).. I also seem to recall a universal bell housing that would fit across the board as it had different bolt patterns pre-drilled so it would fit any GM product. Also they ran two different tail shafts, one long and the other a short tail shaft.

Anyhow, if you currently are running a TH350, just make sure the bell housing on the one you are getting is the same as what you took out, and the tail shaft length is the same,other than that a 350 is a 350.

Buick, Olds & Pontiac are the same & don't bolt up to a Chevy. The Chevy has the round top. The short tail shaft (6") is a car tranny & the long (9") is out of a truck. They also make adapter plates to use either style with either engine (Chevy to BOP or vice-versa).
