Take it too the track and see if E.Ts back up those numbers. I am curious for one. I have never put too much stock in DYNO numbers other than for tuning.

Hmm...that torque curve looks fishy. I agree with track results. Curious to see what she traps!

Looks like it spikes at the end actual power looks to have been leveling around 326ish then turns upward.

Yeah, I'm not sure about the dyno really. My car made 376/381 on a dynojet before the Ported Throttle Body and LS6 intake. I know the dynojet reads higher, but after everything, my car only made something like 333 rwhp and 340 rwtq with a bad MAF sensor (according to the tuner). I know my car makes more than that. I ran high 12.7's @109-110 on Nittos.

I wonder if its some type of Pre-production Head that made it on the assembely line. Check out these heads on E-Gay There suppost to be ported LS6 heads but they have a weired casting number I have never seen before. Looks like 543 or 549 cant tell. I know most castings but have never come across the ones you mentioned. Never seen the ones on E-gay before either...

Yeah but this time it's for a good reason unlike some of the other EPIC threads lately.

I crack up every time I see the title of the thread.

I think mystery head is some sort of deviation from strange.

Yeah, I'd say the dyno measurement was in error after 5341 rpm and the peak numbers are bogus.
