Kamaro

I swapped in a new pair of PRC 227 heads and a small custom grind cam spec'ed by PG (223/229 - .629/.629 @ 115+4) along with a FAST 102 intake with a stock 90mm throttle body. I got the car dyno'ed yesterday and I got 445 RWHP and 442 RWTQ and that only to a 4500 RPM pull because the stock LS2 injectors were maxed out!, my tuner said it will easily pick up 30-40 hp more if I had enough injectors. All that with a 1 7/8 LT headers to 2.5 in exhaust.

Well, these PRC heads gave me what I was looking for and some more!

Thanks for the guys at Texas Speed, they were very helpful both here in the forum and on the phone

Excellent results from a well put together combo, like the cam specs.

Something doesn't seem right here. Hmmm

If you've noticed anything off here then please let me know. I'm definitely not an expert here and I'm willing to know more about my engine.

445hp @ 4500 rpm = 519 ft-lbs torque

At 6500rpm that motor would be at approx 600+ rwhp. Not.

Sounds good. 440rwtq and 490-500rwhp seems possible on the LS2 or 6L motors with good heads.
