I found a 396 last night. What do i need to do to put a 396 into a 67 4x4 frame with a 69 cab. SM420 tranny w/ 205 transfer?? Original engine was 327. After I get the floors in the original 67 cab I will put it back in, but that will be in a few years. Any suggestions. The 396 has headers, do I need to change those back to manifolds to make it fit. I'm new to chevy engine swaps. All I've done is ford engine swaps
