I have been working on placing a 52 GMC 350 on a 86 Chevy Frito-Lay step van frame. It has a 4bt Cummins and Chevy auto trans with over drive. I have the cab and front sheet metal all mounted but I think I need to move the motor back. I would like to get you guys opinion on if I should move it. I am thinking about moving it back 3 inches but I will have to cut the firewall a little at the bottom. Right now the radiator will have to be in front of the Rad support along with the intercooler and electric fan and it will be tight.
Thanks
Brad
