For a race car that will exclusively see the road course tracks, so idle is not an issue, just how much is a reasonable power gain to expect on an otherwise stock engine with custom headers, straight pipe (no muffler or cat) and a decent intake?

Thanks,

Steve

ps - Once developed, the race car will be 2100-2300lbs. Porsche 951

Are you talking about GM's 88958606 camshaft? it's a 239/251 with .570" lift? what is the LSA?

I'm guessing bout 60-70 rwhp based on what I have done with my car.
