502 rebuild and upgrades
I am wanting to overhaul my engine its a 502 mag mpi. going to make a 509 go with promaxx 317 head not looking to get into a debate on this head or that head. My main question is what cam would be a good cam? really would like to get to mid 650hp. boat is 7200 lbs. I plan on upgrading the manifold to a holley and going with holley efi. Thanks in advance

Don't know what ECM you have but Eddie young programed my MEFI 3 to get 530hp
MEFI is easier to tune and I'm sure there are some here with the correct bin files. I have the one for mine
