Cylinder Compression Test Numbers

Do you want a peak hp dyno number? Or do you want usable power under the torque curve? Also, a cam that big will need a fuel system, big converter, gears, headers, etc. That doesn't all fit the budget in your OP. Also wont launch very hard in your heavy truck. Think torque instead of hp. Build for torque, and you will gain hp also. But the hp will be "usable".

For 2500 you can have the bottom end done with fresh pistons and rings/bearings ect, come in with a budget built 370. Runs some cleaner through the fuel system, as long as the truck isn't having a misfire issue I would not worry about replacing coils as of yet. Wires, yes prob so. That cam is to much for heavy truck, unless you want to run a converter in the 3200+ range.
Wayyyyyy too much cam for your heavy HD2500 crew cab.

I want usable torque. I could care less about peak hp. I want to get this beast rolling and want to be able to pull a trailer from time to time... Circle D 278mm 2800 stall is all I really want to go.... Nothing to radical. OK, So I'm getting the vibe to stay away from this cam. So, what spec cam should I be looking at? I know this varys for person to person but I think I have enough info to let ya know what Im looking for but Im not sure how to get there.... Thanks everybody for your time and tips!
IMO no do not fix what isn't broken

The 1500HD is what some called the heavy half. With the 6.0, 4l80e and 3.73 HD rear is def the best truck I have ever owned. Bought new in 2002 and been punished ever since. Im shocked that the compression looks this good after almost 200,000. Cheyy has come a long way since my sb and pontiac days!
