502 mpi too 500hp conversion..
I have a 96 502 that started life as a mpi 415 horse motor. But now I have removed the MPI, and put a dart high rise intake, and a hp500 850 and I have emi exhaust on it. It also has roller lifters and a upgraded merc roller cam. I wanna make 500 horse. So what am I going to need to make 500? Im not sure I will even see a difference in MPH over what I have now...I run right at 70 gps now.

Your heads are the same as an HP500, and your valves are the same size. The HP500 does have upgraded valves, but not for more power, they are for better longevity.
