Can anyone guess my hp and tq numbers? I'm building an LQ4 stock short block, with Procomp heads that flow 293.3 206.6 @ 650.. The cam is a custom grind 247/260 @ .50 .647 .647 112+3 LSA. Ls6 typhoon aluminum intake with 90mm TB, 102 MAF. 1-7/8" slp lt into 3" loudmouth.. B&M recommends a 3000 stall hole shot thru 4L60E and finally 3.73 gears

 

I would think you need more stall than that. A 4000 at least.

I'd say probably 440rwhp or so.
