The Stovebolt Site Forums The Shop Area The HiPo Shop 5.3 in a 55.2 GMC 150

In the beginning stages of my 5.3 LM7 swap.

So far
SM420 in stock location with 66 Chevy V8 bell with 55 clutch fork to factory rear engine mount.
Pass side truck manifold does not clear the frame or rear engine crossmember.
Heads hit firewall on both sides. Either move engine forward about 2 inch or modify firewall is the hold up for moving forward now.

Found lots of info on this swap but none using factory trans in this body style.
