The 235 will bolt up to the GMC bellhousing. Some of the part number crunchers will need to give you some advice about whether or not the timing pointer on the bellhousing and the 235 flywheel will give you accurate ignition timing. I don't think the GMC flywheel will work with the 235, but the 235 clutch, pressure plate and associated parts should mate with the transmission input shaft OK. The 235 engine is a couple of inches shorter than the GMC, so you'll need to do some adapting of the front motor mounts. Exhaust, throttle linkage, and a few other accessories will probably need to be adapted, also. Good luck!
