LQ9 with stock 799 heads, 231/235. .630/.610 cam, 4" cai, e fans, 1 3/4" long tube with 3" duals and H-pipe, 3600 Yank converter, 4L80, 3.73 gears, 29"-30" tires, 4000 lbs truck. Intake, MAF, TB, injectors all stock. What would you guess this makes at the flywheel and at the wheels? I would greatly appreciate your input?.

 

Ima say 450-475 horse at the flywheel just guessing..the 4l80 will eat up some of it though to the wheels

 

Should do around 380-400 rwhp by my estimate.
