Hey guys just curious to see what everyone thinks im running for horsepower. Before the car was bought, the previous owner's kid blew the motor in it somehow and installed a new crate ls1 motor. Since then, i have added a volant CAI, ported the TB, de-screened the MAf, BBK LT's, ORY, AIR!, EGR! and a Hooker Aerochamber cat-back. I will be getting the PCM sent to frost to have it tuned pry by this week. Any other work to the car is unknown as far as mods, the guy was a ASE certified mechanic and put the motor in himself, along with a new T-56 and a new clutch. It doesn't sound like it has a cam in it or anything, but it sure feels a hell of a lot faster than my parents 04 GTO does since i bought it. Thanks for the input!

No one has a guess?

For what's listed, I'd guess somewhere around 340 rwhp. 345 rwhp if the new crate LS1 came with an LS6 intake manifold.

Cool thanks, thats kinda what i figured. And im pretty sure it doesnt have the ls6 manifold on it, it had the long tube for the egr going into the intake manifold.
