Does anybody know if a automatic transmission say a 700z4 tranny will hook up to the V-6 or would that even be a good way to go if it is possible? Or should I just put a v-8 in it as long as I'm putting in a new tranny? Any tips out there in this matter? Thanks  | | |

Anyway in the 70 model year, all GM's transmissions: 3 speed Saginaw, 4 speed Muncie 465 (manual) and TH 350 and TH400 (automatic), would bolt up to any Chevy L6 or V8. Only difference being that manual transmissions require a bell housing. I don't know much about the GMC V6 305, but I've heard it would climb up a phone pole if you put it in granny gear. I would assume it too would bolt up to any other Xmsn of the period, but I don't know. As for the later Chevy V6s, I hear they're just 3/4 of an SBC block, so why not? As for the Th700r4, I also hear it's the same size and fit as a TH350, so it ought to work. Maybe some experts can prove me wrong.
Every 25 years I like to rebuild that 292 just for GP

Measure the lifter covers on the side of the block and if they are close to 6 inches high, you'll need the passenger side motor mount bracket. Shouldn't be a problem putting it in as the frame is already drilled for it. You might also consider getting a wiring harness for the engine to save cutting and splicing wires.
