Default 500 rwhp lq9

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

V/R

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.

^^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.

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.
