By the quick glimpse of the graph it was still goin up at a pretty good rate.......most are skeered to turn these engines for some reason. A ls6 should be good to 7400-7600 with the appropriate cam/springs/intake.

W/o being on the same dyno it's hard to say. Most want to go by dynojet numbers. My dynojet numbers would be 431hp/405tq. My 417hp/395 numbers were made on a dyno dynamics, they are known to be conservative. Before the 1.8 rockers it made 413 on the same dyno.....which is exactly what vetteboy's record ls6 car made. He also dyno's on a dyno dynamics but not the one I am on. They are both full bolt-ons. Like I said if you are serious about making some hp out of them they will do it. Most would rather talk about their cam though.

Briansformula has also been over 400 with his bolt-on ls6.


Good find.....neither of those cars had a fast on it either. +15rwhp for a ported fast on them easily.

A grand am cup cam and gmpp 243 heads will let you turn 7400-7600. Did that to a buddy's ws6.


It's a none issue. Look around on here at all the graphs that stop short or level and they stop turning them. Turn that bitch till it falls off. One problem with turning alot of rpm is the intakes that are available for ls engines. I would love to try a lsx r/t intake if it would fit.....I bet it would free up some rpm and power.

Sweet vette! So it is attainable, awesome! Any 450+ or is 450 the max someone with cam/bolt on's LS6 got. Maybe Hio should be a little more descriptive. He stated "cam only LS6 should make 450+". Stated correctly cam/bolt-on LS6. Another thing, how it "should" make this power. Even after someone stated the LS6 should do that "easy" on that vette site, the builder came to disagree & said it was not "easy".

"Cam only" is always a loaded statement.... it includes bolt ons in this context. As far as the builder... he is there to sell product... he wants you to buy it from him. With the right parts the result should be reproducible (aka "easy") if that makes sense.

The mach 1 could never get me and it pissed my buddy of because that's one reason he got the car. He pre ordered it and all I heard was how I had no chance once he got it. Lets just say he was disappointed ,haha This thread gave me a good laugh.
