For the ones that know me anyway......
504 hp and 449 tq.
I have some valve float/pushrod flexing/spring harmonics going on at 62-6300 RPM. HP drops to 490 and then recovers back to 500hp by 7200rpm. So basically, Im thinking about going solid roller with thicker pushrods and since the heads will be off, Ill knock up the compression. Not sure if Ill need to spray it anytime soon after this, but who knows. Id like to see 9.99 N/A We'll see how taxes treat me. (owning ur own business sucks sometimes)

3550lbs raceweight Iron 6.0L block 4340 Eagle crank, no lightening (crankshaft weighs over 60lbs!) Un-ported heads Definately not a 'race only' or lightweight setup. Nothing special really..... Just a good combo put together correctly.

Wow, definitely going against the norm here. A simple horsepower calculator, assuming a 18% drivetrain loss, would put it at about 723 flywheel and 626 at the wheels...and that's with a near perfect launch, no converter slip, and a damn good driver.
Congrats!

Well his setup might not be the most "Race" one possible but let's look at it this way... it's a 98 Trans AM, the block is not stock, it's a stroker, it has aftermarket heads and fully built engine, it has an aftermarket transmission, and I know it doesn't have the shitty stock V6 F-body 10 bolt rear end. I'm more impressed with an 03 Cobra going 10's stock everything except more boost on the Eaton. Nevertheless that is a bad ass LS1, congrats on your numbers and ET's... good luck on getting into the 9's NA.

0psi > 20psi. There are only a handful of stock heatons running 10s in the country. Impressive combo! I heard some photographer got some sweet launch pics!
