Gents,

I have read quite a few post about massive HP 6.0s and 6.2s, but I can't seem to find if they are doing this with stock L99-LY6 heads. Obviously a camshaft R2 is a must. Can someone point me to a good read that will tell me what to swap out (specifically) on an LQ9 to get 600hp? My TKO 600 needs some love

Brett bauer just did a cam in a ly6 that made 650 crank hp

Some 6.2s might be able to hit that with stock heads, massive cam and every bolt-on imaginable, but there's very little chance 6.0s will get to 500...and certainly not with stock heads.

You basically need excellent and expensive parts to do so, and even then it's not guaranteed.

LQ9 with ported LS3/L92's heads, FAST intake, LT's, tune, and a nasty cam then maybe.

Where can I go for proven combos? Camshaft specs, head work etc? I know the magazines are hard to trust these days.

Magazine articles are good for one thing selling magazines.

I have a lq9 with ls3 Internals I had my block board over to a LS3 Specs a big cam CNC ported ls3 heads do you think it's possible for me to make close to 500rwhp

^^To achieve that 500rwhp you go need a big camshaft for sure!! Maybe even the factory intake ported really nicely. 233/248 duration camshaft will float you around 490rwhp but PTV IS CRITICAL.

First you say 500 rwhp the 600 hp. So which one is it?

Old post but it is easier to do with a manual transmission. If an automatic you have a much tougher road ahead. No matter what you will need a well sorted out combination.
