I need to scan the dyno sheet but it seems near right on as far as were it made peak torque and peak horse power because right after that is were it seems to fall flate on its face.

Got some New Numbers on a DynoJet today!!! Put down 240hp at the wheels all stock with 119,xxx miles on it. All pulls in 2nd same as before. 
This was done at OC GM PERFORMANCE in cypress. They were having a dyno day this afternoon. They are a new sponser. I found them on the LS1Tech side in the Western forums.
So I guess thats pretty good then...
I am going to get the new short block together over this next week. Then I need to get my heads done and work on getting parts for the trans. Hopefull I will have it ready to swap out in the next month.

My 05 LM7 put down 255hp@5248 & 274tq@4043 without tow/haul and 249hp@5411 & 271tq@4074 with T/H on right after. Wheatley 87 Octane tune, K&N drop-in filter, and cheapo muffler with the exhaust exiting before the rear tire.
