I don't think I ever posted up what mine made last go-round. Few changes were made when redoing valve springs and brought down the CR a bit from being higher then expected before. New exhaust setup, and some cooling mods will be going on in the next few weeks.

ported stock castings
hand ported intake
Holley 58mm TB
Lunati 231/239 .570/.585 110
1 3/4" headers/ORG/GMMG
T56 - 3.73s
!AC - EWP - UDP - LS1 lid
EFI 24x setup
Tuned by Alvin at PCM of NC.
422hp - 395tq

Just had mine tuned on tuesday at tpis. I have a 355 with forged pistons and h beam rods on the stock crank. LE 21* tfs heads and cam. 4000rpm stall and 4l60e. With a 9" rear end.
Car made 392 whp and was still pulling at 6700 but was having some ignition issues and had to stop. This was on a dynomite dyno.

1994 Trans Am GT, M6, 100% stock except for Moroso CAI & K&N air filter: SAE 267.7 HP @ 5100 RPM, 310.8 LB-FT @ 3200 RPM.
Since then I have installed a BBK 52cc throttle body, 1.6:1 Comp Cams roller rockers, a new optispark, and a new catalytic converter. I hope to get it dynoed this year before winter strikes.

Basic 383 Brodix -18 headed LTx with a 300 shot. it made 53x N/A through a TH400 and 9in
If we had not burned the valve it should have went just over 900Whp. I hurt it the week before on "E" and this was trying to make the west coast shootout on C23.
new valves on the way pistons TBD
BTW That is at 6,600 It peaks at 7,700-7,900

Not my current set up, but before i had the engine rebuilt. Stock engine with CAI(filter, straight pipe, aluminum elbow, air foil, and coolant by pass mod) Hooker Super Competition headers. Stock 2 1/4 exhaust with the exception of the mufflers replaced with tiny glass packs. It also had 4.10 gears and a tune. It made 295 hp with an exhaust leak on the drivers side header flange. Can't wait to dyno the new set up.
