why not stay with a 302, i mean stock truck longblocks are nothin special an i thought they werent even roller motors but again i could be wrong. why not stay 302? you would need headers an stuff to swap it on..jmo
i wanna do a 351c in a notchback but 4bolt main, 4v heads an a nasty nasty cam over 600lift. you can find these motors if you look around. stock heads flow pretty good. just a thought but good luck an i see no problems with a one car garage as i did my motor swap in the capri in a small barn lol
