have fun... I've heard there are issues with the firewall if you want to run HEI and the crossmember needs to move on 4X4's

Did you have to change the frame cradle that the frame motor mounts attach to? What was the original engine?

I put a bb in my 69 swb 4x4 that originally had a 307. Moved it forward 2 inches. Drilled new holes for the crossmember and moved the clutch pivot forward. No problems with my HEI now. Did change to the newer throttle linkage though (no solid rod)
