Rockman, I am in the process of building a 383. It is a good engine for 4x4's due to the ability to make monster torq down low.
I have all of the parts at the machine shop right now being clearanced. I would say go with a 4 bolt main, so that you won't be limited on HP. I am not sure how much you can push on a 2 bolt.(around 400 I think?)
Just be sure and get a good quality rotating assembly. I bought mine already balanced, so the machine shop wouldn't have to do it. Everything I have is in my signature below.
Everyone on this site has been very helpful. I am by no means an expert (this will be my first engine to build) but I am keeping everyone up to speed on my progress, and asking lots of questions as I go.
Good luck with whatever you decide.
