Hey guys i have a s10 i put the 4.8l in and recently got a 6.0 LQ4 for it...well doing some research i was wondering what was changed between the motors to give the yukon xl2500's 20 more HP then a silverado if its the same motor??? different cam? tune? heads?
Same motor, probably in the tune. What year model is it?
Mine is a 2000 motor with 300 hp.

The yukon Denali has 20 more hp then the regular 6.0 but it is still a lq4. the esclades, vho, and sss have the lq9 with 345 hp 380 tq.
the Denali has 320 hp 375 tq. I am not to sure what they did to get the 20 more hp
i almost bought a denali motor so i did some research on them
2004. they both have the same torque just 20Hp difference...
from my understanding is they are the same block and everything. the difference is the LQ4 has dished pistions lower compression and the LQ9 has flat top pistions high compression. from my understanding that is the only difference. LQ4 is a better application for boosted applications
both applications have the LQ4 with the 20HP difference...i know the differences etween the LQ9 and 4 but there both LQ4 and the silverado has 300HP and a hummer has 325...yukons have 320...all LQ4's
it's called marketing
