your the man just the kind of stuff I like to hear I'm doing a LQ9 s-400 turbo e- bay front mount 02 ls6 cam maybe e-85 or pump gas with meth.What injectors are you using?

i dont know how much power you loose on a 4l80. I have a gt4276 on a stock ls1. 17 degrees of timing, 6 psi i made 442/467 floating valves. My power peaked at 5,000 rpms. With valve springs im guessing i will hit 470/490 @ 6 psi. Im on a mustang dyno with a t56, and have a 10 bolt with 4.10 gear(yea i know it sucks, 9 to be ordered soon)

torque looks great, but im not sure about hp.

sounds alittle weird, horsepower should be a bit higher but overall i think the conditions might be one of the biggest factors, torque looks real good though and pretty close to the "norm" at 6psi . Where are you located btw???

I'm thinking cam and springs are in the order, she has a truck cam, and I'm sure it's not as big as LS1 cams.

Real great stump puller!

60lb injectors also.

HP does seem low but tq looks good. I made 341/363 rw NA with a small cam on an otherwise stock LQ4/4L80. With 8psi we made 520/507 through an 80 with a 2800 converter and 3.42's.
