Quote: what camshaft are you currently running to make 451hp? Your torque seems a little light. The LS6 makes 400 lbft torque in stock form. I'm currently trying to hit 500 with my 01 LS1. IM Prepping a set of 243s
And he said stock cam...

whp my man! 500hp at the crank isnt too difficult with a 5.7 especially with some prepped and decked 243s. Warmed up 228-232 intake and 230-238 exhaust cam, Fast or MSD intake, full exhaust will net ya 5 at the crank...5 to the wheels is a bit more difficult.

500 at the crank is bolt on ls6 territory


500+ whp......isn't that hard. Personally i think 600whp out of a 5.7 is doable.....and not really that difficult.

All with 243s.

While this may not be exact head but PRC 237 had slightly better results vs. TFS235 on a 408 a while back. I was surprised and impressed with them.

I’d just go TFS or MMS .
