Hey guys, what is the overall best cam for a 4.8L.

I am getting my income tax back soon, and was looking at a cam for my truck.

So far all I have done to my truck is ASM headers, with full exhaust, UPD intake, and Nelson tune.

I want somthing that will pull pretty much within the whole RPM range, and preferably a strong low-midrange power.

What to you suggest?

thanks,
