I just picked up 30k mile LQ9 out of an 2004 caddy, i am going to do the swap in the spring when it warms up i little bit.
My questions are with my bolt ons what is to be expected for hp? with, efans, nelson tune, full exhaust,CAI.
And then for the drag race crowd what could this setup net? with 4.10's true trac, huge trans cooler and a 4250 lb race weight.

anybody got a cam and stall ??

 

I can't help you as far as horsepower and torque go. But Back in 2002 a friend of mine blew up his 5.3 so he bought a 6.0 out of a 2003 Cadillac EXT and put it into his 2002 Silverado kcrb. His mods were ASM equal length headers, 2 1/2 exhaust ran through 1 chamber flowmasters, 13 inches of lift, 4.56 eaton's front and rear with 35x12.50x16, hypertech, CAI, and a shift kit. He could make that big *** truck make noise in second gear like it was a 4 speed with a granny low. It wasn't anything to play with as far as a 4x4's goes lets put it that way. I think you'll be very pleased with the results, and as far as a with a cam and or stall you'll be even more.

 

With an LQ9 and those mods I would say you should be in the neighborhood of 390-410hp. You should be able to run somewhere in the area of mid to high 13s at the track IMO, provided you get traction of course.
