Re: 4bt cummins swap
I've got a 4bta in a 61 gmc 4x4. I used a late model frame, it makes getting parts easy. I love mine. Dieseldude helped me a lot on my build. Unless you go with a add on OD drop the 4 sp and look for a 5 or 6 speed.
Don't let the numbers fool you they have all kinds of power! Enough to rip gas componates apart
