Engine/Transmission Swap


Asked by Jun 03, 2013 at 06:48 PM about the 1984 Pontiac Firebird SE

Question type: Car Customization

I have a 1984 Pontiac Firebird S/E with a V6, Rochester 2 barrel Varajet Carb and the
700r4 stock automatic transmission. I was given a 1968 Pontiac 350 engine with a
Rochester 2 barrel Varajet Carb that I plan on rebuilding as it has sat for 7 years.
Can I put the 350 into the 84?  Will I need new motor mounts and a new tranny?  If so,
what tranny would go with it?  Turbo 350?  Turbo 400?

If you are just rebuilding to stock the 700r4 will be fine and should bolt right up, there is also a kit that costs about $125 to rebuild the transmission, it has a larger servo for the band and a Kevlar band, I think the kit gives the trans a disability rating of 500 hp. Worth looking into, the 700r4 was used on "PRETTY MUCH" all rear wheel drive GM vehicles up to the early 90s. That was capitalized and quoted because it wasn't used in all rwd vehicles just most.
