it was like 105 or 108 if i remember right. I started to pull the motor apart and everything is looking good on it. Cylinder walls look great and doest have much if any lip on them. Ill pull the crank out tonight and look it over. Im going to keep my heads if not sure what they flow but they were CNC'd but im going to get them flowed. Im going to get some bigger pistons and maybe bump the compression up little and get a custom grind for it. New injectors, fuel pump, and new tune.

Mph is way off. Are you sure the tranny wasnt sliping? Also what kind of stall stall are you running? Try and your get compression around 12.1.

That sounds like it could be an issue with your programming, ie. locking the TCC in high gear. It would KILL performance if it locked prior to ~6000 rpm at WOT!

I didnt even think about that, its like its put on cruise control and wont turn up much more when its in high gear. I know when I put the 9'' with the 4.30s in the car didnt pick up hardley anything from when it had 3.23s which I thought was odd. 60' didnt inprove much either and the car never spins and runs consistant everytime.

6500 or so which I dont want to keep turning it that high to much. I got some time to pull the pistons and crank. So now pretty much I need to just buy the pistons, send the block out to get it bored and pistons pressed on along with new cam bearings.

Damn straight. If your machinist doesn't bore with pistons in hand and NUMBER the pistons, fire him.
