1999 silverado ecsb 5.3L, gibson exhaust, gutted cats, cai intake, vette servo, TB converter, and hp tuned by me. now need ls6 cam and springs.
1995 1500 rcsb got a 12 bolt rear end, PLAN (6.0L swap with 4L80E. fuel cell, cam, valve springs, rod bolts and spray.)
LQ4 is lower compression that has dished pistons. It can be found in HD trucks,vans, H2's and Denali's.
LQ9 is higher compression with flat top pistons. It can be found in Escalades, Silverado SS & Vortec Max.
I'm not sure there is a way to tell just by looking at them unless you can get a peek at a cylinder.
