64 C10 Engine swap

[j.rigby15r]

Alright, so I am a long time follower of this forum but a first time posting. I just bought a 63 C10 long bed last night and I am getting ready to go to work with her. So I bought her with a small block 305 with a th350. The 305 has a cracked head but the tranny is good. I am wanting to swap the 305 for a 350. From what I have read the swap should be really easy (if not let me know). What I am trying to figure out is, the engines I am looking at putting in her come from a either a 86 (carb), 350 or a 91 (TBI) 350. Which would work best and be easiest. I am looking for a quick swap so I can get her on the road. Both motors are the same price and require new rings and probably valve seals. So it is a matter of which one will work best. Any input is appreciated. Or if anyone has a better idea I am open minded. Thanks.
