350-400hp budget build 360 ideas???

Rick thank you very much for the detailed info i'm definitely looking into that website it looks like they are very affordable i'm narrowed it down that i'm gonna take my block to the machine shop and have them hot tank it and then see if they have to bore it at all from there, i'd like to clean everything up like the crank, rods, heads etc and then start purchasing a set of pistons. how much would you guys say the basic hot tanks runs?
