Well I looked at his Logs and I think I know why his 60' was so bad... 126* iat!! Bad heat soak! It didn't hit full timing till around 57 MPH. He never hit more than 21* by 20mph and no more than 24* in all of 1st gear... Plus he was gettin some false knock at the high end of third. I need to make a few changes to his tune, and we need to redesign his intake.

Thanks guys, its a good start i think, looks like i need it do a little intake work and maybe a 160 stat to try and get the air a little cooler, and little a more tuning work and a good track day maybe i can get it into the lower 12s were it should be.

I've ridden in the truck quite a bit and it seems to have really good low end. Especially for the size of the cam. You can't reelly feel the low end with that stall but when the converter locks up you sure can! But his stall don't feel nothing like what a 4000 should. He took it out earlier today and tried brake stalling it as hard as he can with the slicks on it and all he could get was about 2500 rpm... Seems kinda tight for a 4000!
