We have a diesel conversion section in the engine area of this forum with a lot of builds in it as well.
Thanks! Good feedback…My goal is to be able to compare the small block fore and aft and then find the location for the Cummins, so I do not have to cut the firewall. I’ll be using electric fans to make room in the front.

I’ll check out the diesel section. Perhaps I’ll find a “common” Mopar crossmember to Chevy frame location on the frame I can use. Would you know of such a location that I can map out on the frame?

I do plan on replacing all leaf springs and am hoping for a 4 inch lift while using the Dodge front and rear differentials (reportedly with 3.08 gears). I need to gain knowledge of a spring pack that will hold up the heavy weight of the Cummins while getting the 4 inch lift. Do you know of a leaf pack package that I could purchase to accomplish this?

Any help is accepted and appreciated. The easier (through other’s experience) the better! Thanks!
