Assuming you are going back to the seventies, Buick, Cadillac and Chevy had the same bolt pattern. Then Pontiac and Olds had there bolt pattern. Breifly GM did supply hydramatic transmissions with both bolt patterns. So, if your transmission has more than eight holes ( two for the dowel pins) on the bell housing it should fit ether.
No. The Pontiac headers will not bolt up to the Chevy small block.
only a Buick, olds or Pontiac engine will bolt to a Pontiac tranny as Chevy blocks have a different bolt pattern.
yes
Chevy to Chevy...yes.
Anything can be done with enough work. However after 1981, f bodies had chevy engines rather than the Pontiac. The Chevy trans will not bolt to the Pontiac block willingly.
no the 2.2 uses the small corporate bolt pattern also used by the 2.4 "iron duke" the 4.3 uses the standard small block chevy bolt pattern used by 305, 350, and 400 small block chevy motors. (Not the same as Buick, Olds, Pontiac)
No, not even close. Pontiac 350 intakes will interchange with 1965-1979 Pontiac 389,400,421,428,455 intakes. Most all aftermarket Pontiac V8 intakes are designed for the 1965 up bolt pattern. 350 Chevy is part of the small block Chevy engine family, and virtually nothing interchanges with a Pontiac V8.
Yes, it will.
No...it will have the bolt pattern of the Pontiac, Cadillac, Olds and Buick. Chevy has a different bolt pattern. There are some transmissions that do have the dual bolt pattern, but I don't think the TH 400 was one of them.
No such engine as a Pontiac 400 Big Block. The back of the Pontiac engine block has a different bell-housing bolt pattern than the Chevrolet. Pontiac and Olds bell-housing bolt pattern match. Chevrolet and Buick match. Unless you have a dual bolt pattern transmission (GM did make them) the Pontiac engine won't bolt up to the the Chevrolet transmission.
Some Pontiacs came from the factory with Chevy engines. If this is the case on your 79 firebird, then the transmission will bolt up to a 350 Chevy. If the car came with a Pontiac engine, then the bolt pattern is different and would not bolt up.
No, the tranny has to be out of a olds, Pontiac, or Buick to bolt up to a Pontiac engine.
