You are not going to get to 500HP on an RV cam. Nor is an RV cam suited for super/turbo charger. You need to get one suited for forced induction. Also you are going to need a roller cam and full roller rockers. Both these will probably net you 50HP+ and some MPG. A solid lifter is also going to help you get to your power (and you are going to have to adjust valve lash every 3,000 miles).

What pistons do you have? I hope for the $3,000 you have invested thus far you have some flat tops (factory dished pistons are not good for performance).
I told him as he was tearing it down... and so he changed to order forged pistons.

OK, so I'll ditch the RV cam. I'll look into the heads as well. Would I need to go aluminum? I'm not concerned with the cost, but if iron ones will do nicely I'd prefer them. The pistons should be flat, but I'll find out which ones he installed.

So next would be looking into some cams and internals that would work in harmony to best suit an attainable 400+ hp. Can you name a few that would be wise to look at and would work together?

The more I'm reading, the more I'm coming to the reality that 500 was just a number I focused on. But I'd still like to get as much as I can with a strong power plant under the hood.
