CHEKT OUT

Ok heres a good one for anyone with with any knowledge, I want to build a cool engine with some big power out of some parts apound the garage. The plan is a full forged Eagle bottom end, 540 or 502, GM performance marine heads with oversize valves, cam choice is still open, full mercury racing 525 EFI and a M1 procharger pushing 5 lbs. I know I'm asking for trouble but I've got a good background in engine assembly, tuning, programing ect. Just looking for some insight and advice. Thanks in advance for the info.

M1 is too small. Too much heat generation on a 502, never mind a 540.

At least an M3SC or larger and the big intercooler!

I'm runing a 540 with an M2 - 7 lbs - (no issues yet knock on wood) - 900 hp on dyno.

Better bottom end then eagle.
