I did a lq4 6.0 swap almost completely stock still even has manifolds and cats. only mods are off brand intake and magnaflow cat back. We got 316 whp and 350tq out of it with hp tuners. Is that good power for a mostly stock lq4?

 

how it compares is beyond me, but I'd be grinning from ear to ear with those kinda numbers, especially being bone stock with a tune. Sweet action.

 

i was till i pulled in my garage and bumped my old 4.8 and scratched my painted grille.

 

what kinda dyno did you put it on?

they all read different, if you got those numbers on a Dyno Dynamics then thats pretty sweet!

 

dynojet sae corrected.

 

what gear was the pull in? i assume 2wd and 4l60? what gearing?

 

numbers seem really high to me, i doubt you made enough power off of tuning to make up for ALL drivetrain loss... (within 10 hp/tq) from engine rating...

 

Those numbers are a bit high. The LQ9 in the VHO and 2wd SS trucks make around 290-300RWHP stock and that is through a 14 bolt rear, 20" wheels, and a 2 piece steel driveshaft. The LQ4 and LQ9 are pretty much the same other than compression. Picking up 25RWHP from a cat back, CAI, and a good tune are easily possible. Looks like your LQ4 is just taking advantage of the lower drivetrain drag to make up the power difference in loss of compression. I would say it's not out there much at all.

 

pulls in 3rd gear, stock 4l60e and converter, 2wd truck, 4.10 gear. maybe i have a lq9 and don't know it?

i ran a 14.4@96 mph with a 2.2 60' full street trim on 20" wheels with normal street tires

 

Torque looks good
