Wow. Incredible numbers. Since its an 05 ECSB 4WD truck, it very well could be the HO 5.3L. That was the first year they were optioned in that truck. Its amazing what flat top pistons, aluminum heads, and a slight bump in CR will do for ya!

-I agree that these are great numbers.Originally Posted by txarkitekt
-What would ID the OP's truck as a "HO"?
99 C5 cam/boltons 400rwhp
10 Sierra CC 6.2
03 Suburban 5.3
Look in the glovebox for the option code L33 or LM7. The L33 is the HO 5.3, the LM7 is the standard 5.3.

Great numbers for sure out of an older 5.3. I bet it's a HO L33. I've never seen that high in a NBS 5.3.
