122,000 mile stock bottom end LS1 with back to back comparison. Not even a strong car only put down like 332 rwhp with bolt ons. Buddies 04 gto m6 with ported heads, trex cam and fast put down 406 rwhp on the same dyno, also FM-14 cam + fast 90 m6 01 camaro put down 389 rwhp. Sorry a lot of people try to throw something together and not get the results I got. Flow numbers don't mean **** really, all the tsp heads flow 300+ cfm but you don't see any 224 cam'd tsp head setups making 440 + rwhp. https://ls1tech.com/forums/dynamomet...nderdrive.html I doubt everyone spends 15 hours porting their fast either, how many people do you think take it all apart and actually see if it lines up on their heads? I'll tell you what some of the ports are blocked pretty damn good.

Not to mention 365 rwtq @ 3000 rpm and 399 rwtq @ 3800 rpm is almost more torque than any LS1 / LS2 setup has put down. Funny how when you get a cam and valve job specced out by someone who actually knows what they are doing the results pay off huge. Also funny how this little cam makes so much low end torque and pulls to 6800 rpm no problem. I'll tell you dynos don't make up torque curves, but get your **** setup by a professional who actually builds engines for a living and you may too see similar results. You're the first person yet to call bs, but you're the least educated about my setup. Do a little research next time. A valve job on these heads will go a long ways, a proper valve job that is.

 

something else is wrong and its not the gears!
