Muncie 4-speed into a '79 TA with 455 and TH-350
« on: February 17, 2018, 11:34:27 PM »
Hello all, I have a chance to buy a '81 Firebird as a donor car that has a Chevy 350 and a 4-speed Muncie.  Don't know which Muncie it is yet.

My question is, would it be a major project to swap the 4-speed to my TA with Pontiac 455, and put the auto in the donor with chevy 350?

I don't mind sacrificing the donor to junk if I cant put the auto in it, but really want the TA to be manual.

Thought?

the muncie will have a chevy bolt pattern bellhousing that wont bolt up to a pontiac engine.  i think they make an adapter plate or you might be able to locate a pontiac bellhousing & bolt the muncie trans to it but you will have to confirm that. 

muncies are usually worth a lot to the chevy guys so i would suggest selling it & buying a st-10 4 speed that is correct for these cars & will bolt right in. 
78 w72 ws6 4 speed
81 turbo pace car
