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
