Two different avenues at moment, building a 800 hp NA 548 to run on dyno, going to see how far the modded 500 efi intake takes it, prob wont break 700 with it but well see. Depending how much hp/tq it makes all in with a good intake will determine IF it gets modded 500/525 stuff (doubtful). Meanwhile, freshening up my 500's as back up motors because the 13-1 na548s may /may not be reliable longterm once they are in the boat. The 525 tb and flame arrestor have proven to be great way to add 12 to 15 hp on a cammed 500 efi
