Feel like 360 should have more power

You could trick the engine into thinking it has more compression by replacing even a similar duration cam with one having a narrower lobe separation angle.

As others have stated, high elevation coupled with low compression and big cam are not a marriage made in heaven.

Power can be made with lower compression, and challenging elevation but cam specs are even more critical in this instance.

Job #1, proper tune.

Job #2, find out exactly what cam you have now.
