Right now my mods are corsa cb. kooks 1 3/4, VR AND SPACER, UD PULLEY, 2X CAM, HIFLO CATS AND XPIPE. IF I WAS TO PORT MY TB AND INTAKE WHAT KIND OF POWER GAIN SHOULD I SEE. (Currently 430whp and 391tq)
Scotty I'm going to go out on a limb here and say 8 to 15 hp with porting the stock stuff. My brother just did a Cartek 3X head and cam package with a ported F.A.S.T. intake, Kooks 1 7/8" headers, underdrive pully, and his dyno'd at 507 rwhp. You might give Cory Harris a call at LS2 Portworks, he's the man for porting the stock stuff, he can also do a F.A.S.T. intake too.
With all the mods you currently have the porting of the TB & Manifold
should get you another 20 hp although many with similar combos have reported hp in the range of 485 HP. Maybe im missing something here
did you mean a g5X2 cam ?

8-15 RWHP is the normal. There is a variation due to core shift while casting. We also offer the intake and throttle body ported as well as others. We have been porting stock intakes since 97 and can do them exchange.
Due to the cam, I would expect you to make power on the higher side, 12-18 HP.

Thanks for the referral, Vettl83. I appreciate that.
I can definitely help Scotty get to where he's going with the porting I do. I've got many, many satisfied customers on this board as well as others across the country. Let me know if I can help you reach your goals.
