Doing some research on dyno power levels between a 6.0 vs 6.2 ls motors and how much power does the extra.2 liter give. Here is a dyno of a ly6 6.0.
The blue is with a Ls3 cam, the red is with a Lq9 cam(443hp, 467ftlbs), which is the same as the Lq4 cam. This motor has 9.6:1 compression. Here is the source: Converting a Truck LY6 Engine into an LS3 for More Power
Here is a dyno of a 6.2 with a Lq4 cam.
Here is a truck 6.2 with a Lq4 cam and it shows 445hp and 460ftlbs which is the red lines. The blue lines are of a stage 4 cam. This motor has 10.5:1 compression. Keep in mind the two graphs start at different rpms so that makes it a little harder to compare. Here is the article...

Dyno Test: 120+ HP Gains and No Low-End Loss with Cam Swap on 6.2L LS Engine
Why were we so excited about swapping cams on the all-aluminum L92? Many reasons. The first was that we had previously run the Summit Stage 4 Pro LS cam (SUM-8711) …
