[cornerstone]

I’m doing this same swap on a 72 SWB. I have custom made motor mounts that I will weld to the crossmember. I placed the cab back on the frame to verify that I would have enough clearance from the firewall. Turns out I can slide the whole setup back possibly another 2.5 -3 inches. I’m wanting to know if there are any other reasons not to do this. I’m going to mock it up with the brake booster to verify clearance there as well. What would help me is to know how much room is actually needed in front of the harmonic balancer, so all of the needed components will fit nicely. If anyone can share the distance between their front most crossmember to the harmonic balancer it would speed up my build. Otherwise to be certain I would have to mock up the rest of the front clip as well as fans and radiator. By the way I will have to order a custom driveshaft anyways, so that’s not a problem...
