@rfs56trk and Longbox55........Thanks for the info, I appreciate it. The overdrive is something I'll give thought too. How hard is a sm319 to find? I googled it and all I found were parts listings, no transmissions.
@Cletis.........As I stated, a 283 was an option for the truck, that's my reasoning for saying I wanted to keep it as original as possible. Granted, it won't be original after the engine swap, but it'll be closer than if I put a 350 in it. I've got a radiator shroud to put in it and if that don't do the job, I have fan spacers.
