I am building a stroker 360. I have a 72' 360 block .030 over. I am going to use a 4" stroker crank (does the crank need to be forged?) Edelbrock performer rpm magnum heads and all the magnum parts for the top end to get the pushrod oiling system. Is 500 hp going to be easily obtainable with this setup? will the block handle this hp? It will have roller rockers, and I'm pretty sure someone makes roller tappets for the LA block. Should I be using a Single plain intake for better performance? Thanks in advance
