so probably a 3.1-3.2 given i dont have the nice heads, or the cam that you do to make 10psi. ill have the 90mm tb, 4" intake, and sd tuning like you.

 

You will probably need a 3.0 pulley to make 10psi. Bill has a higher compression engine.

 

I have personally seen at the dragstrip recently a 122 on a 6.0 do 10.9 back to back to back! It was in a vette,but still a maggie.....btw the vortec vette with similiar mods did 11.5's and both hit the same trap speeds.

 

my truck 2008 awd tbss 5135lb@12psi went12.0@ 113 back to back w/112h,think the h flow's better.w/a 85 shot the boost went to 15psi and it went 11.55@118 that is w/a 2.9 pully.stock ls2.i think if you are going to go with a bigger motor later on get the 122h and call it a day.if not the 112 is a great s/c the low end is crazy.i dont see any problem's w/heatsoak.
