Just had heads/cam Stage II install by Norris Motorsports. Dynoed before at 316rwhp....after at 385rwhp. If I can get the PL program right...its goin see 11's.
I've never heard of anyone getting over 450rwhp with just H/C, not saying that no one hasn't it's just that i never heard of anyone doing so. I know a few Z06's have gotten pretty darn close though.
Looking at your mods and your rwhp you got a pretty strong car. My guess is you'd get around 420+ rwph with a stage II H/C.
I also have a MMS package: mild cam, (218 dur, on a 114 lsa) and Stage IIx heads. Great combo!. No loss of low end response, better than stock gas mileage, passes smog, and outstanding HP/torque. I reccomend Morgan Motorsports, they'll treat you right. :chevy
