I got a 2006 Gen 6 marine 502 model # 12568778. I have upgraded to imco power flow exhaust and edelbrock air gap performer rpm and msd ignition. 850 demon carb. the motor is in a 20.5' placecraft skier with setback Berkley. I want to put a bigger cam in it to take advantage of the induction and exhaust improvements. Any suggestions or experiance with a upgraded cam. I believe the motor is a 450hp motor stock. Thanks Jason.
