I know this is an old post, but I was just thinking about the engine setback issue.
Seems like if I am willing to make some motor mounts a B/RB engine could move back (and in my case down) maybe more than an inch once I get the dizzy from the back to the front of the engine. In my (SB) car the dizzy is the 1st thing to hit the firewall.
Anybody ever measured how much further back a BB can go compared to a SB?
