Is the transmission a mate/match? 1967 Jeep J3000 327 Vigalanti motor w/ 3spd on tree to a 1972 Buick 350 The 327 does not run...wondering how hard it would be to transplant a Buick 350 motor into the jeep with hopes the motor, transmission bolt together? He also has a 1966 Jeep heavy half with a 327 vigalanti motor w/3spd on floor. Will that bolt together? (to the 350 Buick motor) Or bottom line, I need a different transmission. Would the transfer case be an issue for a different transmission?
Swapping from the rambler 327 to the Buick 350 or even 455 is not impossible, but not a direct swap. I have performed a swap on 2 different 67 J-trucks. Both were 327 3 speeds. You will need the frame horns/motor mounts from a Buick powered Jeep or make your own which is not that tough either. I do not believe there are any bellhousings to put the 3 speed on the Buick engine. There are 2 options you could go with that I know work using factory parts. 1=find all the parts to put a T18 4 speed in(bellhousing, flywheel, clutch linkage, and specific T18 with correct input shaft, adaptor for trans to transfer case). I hunted all that down "once" and found it was very tough to find and expensive. 2=T400 short shaft auto and adaptor to mount the T20 transfer case. T400's are easy to find for Buick bolt pattern and the T-case adaptors are readily available from any J-truck that had a T400 and a T20 case. That combo was used alot through the early to mid 70's on Buick powered trucks and the earlier years of the AMC power.
