Ok i found someone selling a rebuilt 350 motor on craigslist, but its only the heads and the block, it still needs, a fuel pump, intake, and injector.... I have a 305 TPI In My 86 Trans Am, I wanted to know how much would a intake and fuel pump cost, and if I could just take the TPI off my 305 and put it on rebuilt engine and also they said that the motor came out of a 1995 Chevy Pick Up, would I be able to drop this in my 86 T/A and would it bolt up with the 700r4 are would I run into problems

 

No problems with bolting up the TH700. Use your '86 flexplate and starter.

The TPI will almost bolt up to the '95 engine. The center two intake mount bolts on each side changed angle in '87. You can either get an aftermarket base to fit the heads, trade your base for the '87-up version, or elongate those bolt holes in the base so the bolts will fit.

 

You would definitely have to have some tuning done to properly run the 305 TPI on a 350, it will run but not as well as it should.

 

'86 is MAF. It'll adapt to it immediately.
