Thinking of upgrading LS1
I recently turned in my company car which was a Challenger RS Scat Pac with 485 hp. I'm back to driving my 02 WS6. I really miss the power of the Challenger and have been thinking of upgrading my LS1. I'm looking at cams, throttle body, intake, rebuilding the heads or replacing them, etc. Summit has a kit from Trick Flow that boasts 515 hp and 460 ft lbs torque. Anyone have experience with that company, or any build suggestions? I haven't dug into an LS yet so any suggestions would be appreciated.

I forget the LS1 bore, will the LS3/L92 heads fit? The intake valves may be too big.
I've provided custom cams (VERY streetable) for a few LS3's. Stock except for headers, valvesprings, exhaust and tune, that have made nearly 500hp at the wheels.

LS1tech. com is the place to go for any and all info LS related. You will have days worth of reading and recommendations there.
Good luck with the upgrade, they wake up with very little input.
