[Mr. Don't know anyth]

I have inherited my grand father's 65 c10 long bed. Body I near mint condition minus the sea foam green paint. The problem is I have never done a motor and tranny swap. I have stumbled apon a 350 with tranny out of a 70 Camero. I'm swapping motors because my brother blew the head on the original motor. He drove on it for months.

My question is what do I need for the swap ?

I have all tools available to me. I want to keep the 3 on the tree, but just for looks. I'm going to put the shifter on the floor. Which is automatic. Any help would be greatly appreciated
