I have AFR's on my 89, I just bought a 91 GT and that is the one i'm putting the GT-40 heads on. They are the GT-40X performance "turbo swirl" aluminum ones. I should make more then 310 hp right?
I am planing to put a s-trim on it in the future, and whats the profile of the lunati cam?

I also have underdrive pulleys, a holley systemax intake, roller rockers, and MAC full length headers. Is the 310HP estimate still accurate?
