255 factory which with 30% driveline loss is under 200 at the wheels or right around 200 with 25% loss

 

I would like to know where he got hooker long tubes for that truck because as far as I can see they don't make them for those trucks. If they do then I have a couple of buddy's who would be all over those. All I am seeing in jegs is hooker competition headers for 1988-1995 tbi 2wd 5.7's. I think those numbers are bs, I have a friend with a '97 silverado with dougs headers, msd wires, 2.5 true duals with high flow cats into a dual in dual out flowmaster 40 series, k&n fipk, and harland sharp 1.6 roller rockers and his truck doesnt feel like it has any where near those number.
