For instance, if I were to purchase the T-Rex but instead of installing it straight up, I wanted to advance/retard the cam so that I can move the powerband "lower/further back." If I did that so that I dont have to spin as many rpms, what else is affected? I dont know which moves the powerband down, advancing or retarding. But anyhow, lets say I advanced it 2 degrees and it moved the powerband from 3500-6700 rpms, to 3300-6500 rpms. Would I still have just as good a chance to break into the 10s as those shifting at higher rpms? Is there any drawbacks/disadvantages when advancing or retarding a cam?

If moving the powerband lower is possible without any negative effects, then how come this cam isnt be used more widely for those who dont/cant spin the higher rpms that it requires?

Advancing the cam makes the engine come on the cam sooner and retarding it delays it, to a point. If you have an engine that is already running with a cam installed straight up and you gain alot of power by advancing the cam then that is a sign that the cam may be too big, and if you retard it and gain alot then it is a sign that the cam is not big enough. There is always loop holes in every theory but there is mine.

The TReX needs to be installed at a 108 ICL. If you plan on trying to advance or retard the cam, you better be ready to flycut your pistons. PtV is already VERY tight on this cam.

My personal opinion is that you should install the cam the way it was meant to be installed. If a cam doesnt suit your application the way its ground, pick a different cam.

Also, you won't make the same peak numbers with the cam retarded/advanced. They'll be slightly less so
