Does anyone know of a proven head,cam upgrade for the 454mag MPI. I've already upgraded fuel systems and exhaust...Would like to add a 100 ponies,, Realize ecu will need to be reprogrammed or upgraded as well... Looking for comments...

For what you would spend on a cam and set of heads you could pick up a nice used Procharger and pick up at least 100hp. You wouldn't have to tear the motor down either.

If you are set on heads/cam, I'd call Bob at Marine Kinetics. He did a helluva job on my cam in my LS project.

Check out this thread...Yeah, its a 502 but same intake/efi system.... http://www.offshoreonly.com/forums/g...n-my-shop.html
