Well, I have an 02 Camaro Z28. Basically stock, it is an m6 (six speed manual). It is the ls1. I have slp air lid with k&n filter, Comp cam ls 3-bolt cam, Hardened pushrods, Brian tooley dual valve springs, ls2 timing chain, Ngk spark plugs, Texas speed 1-3/4 longtube headers, pacesetter 3" y pipe, slp axel back loudmouth with tips, and slp underdrive pulley. Car was dyno'd at 367 hp and 382 tq, only has 50k miles on it. Now if I were to buy ls6 heads what do you guys think my numbers would go up to?

 

What dyno? Mustang dynojet?

Numbers are numbers but I have to admit something seems off to only muster 367rwhp

Maybe you need a tune but since you wanna know about ls6 heads it really depends on the whole package you might gain 120hp or 40hp

Just an opinion so don't take it to heart.

 

It was a dynojet. But yeah kinda figured it wasn't where it should be, or the dyno was wrong. I honestly don't know. But yeah I'm going to get it on another dyno and get a tune and see where it's at. But thanks
