Help with 340 rebuild - Chicagoland area

Well as a update, I made a probably bad financial decision and snapped up a complete 1970 383HP that was originally in a 1970 roadrunner supposedly. Supposedly ran when pulled, has oil still in it and turns over. I guess now im gonna go through that instead or something, I dont even know what I'm doing with it yet. I hope I could get at least 400 horse out of it.
