The project came with a 292,which I didn't know till I got it home and ran the numbers on it. I thought that was pretty cool, not knowing the extra hassles involved. So I reattached the bellhousing and transmission to mock up the motor mounts. After getting it into position I realized the front crossmember on the chevy chassis was a little different from the GMC member. So 24 rivets later, I have the GMC member mounted into the chevy chassis, using grade 8 bolts. I found that I could grind 2 slots into the rivets head, then air chisel the head off, then air punch the rivets out. Got it down to less than 2 minutes per rivet. Welded up some chassis mounts using some roll bar tubing I got from a friend. Thought the tube would look cool.
