Re: 67-72 BigBlock 4x4s! Pos pics info here.
When i did mine over 10 years ago, i used stock 77 gmc 2wd exhaust manifolds but i had to grind the little nubs off. Also used the original 350 engine mounts. I put on the corvette style valve covers to get a little more clearance by the firewall, but had to grind just a little off the back lip on the drivers side. When i do it next time, i will go with a smaller dist. like a unilite, or mallory. The stock HEI is against the firewall right now. Everything was pretty tight, but it all went. I think i put a small dent in the firewall where the HEI sits. I hear a body lift makes it easier, or i know a guy that moved everything forward to the next set of holes in the frame. Eric
