I took some time and searched and wasnt really able to find an answer. I have a 1949 GMC 1/2 ton truck. I just got done rebui8lding it about a month ago. I put a 1970 Chevy 20 motor in it and fabricated a front cross member. I had a small block bell housing adaptor that i used to bolt it up to the origianl granny 4 speed tranny. I came across a extra small block that i have out of one of my wrecked corvetts. So i think i want to put it in. But i need to know what needs to be changed to put it in.

I was going to get one of the already made cross members from chevy duty for the small block. But what else needs to be done. Is the steeing box in the way? Is there anyway to keep it where it is using a specific header? Basically, what needs t obe done to put a chevy 350 into one of these trucks? Thank you all for your time.
