he is saying that cam is too big for the 4.8. You can get a smaller cam that will work better with a 4.8 and still have that muscle car choppy idle sound. There are plenty of trucks on you tube you can find with cams and listen to them. I understand what your saying, your not going for all out fastest truck, but you want it sound nasty like it is. If you get a cam with tighter lsa of 110 to 112, you will still have that choppy idle.

I believe its a Howards cam. I ordered it from Thompson motorsports.

LSA will affect your idle and powerband. As a general rule lower LSA will lead to a choppier idle and will move the powerband lower in the rpm range. In your case this is a very good thing. A 4.8 lacks torque and will really benefit from lower end gains. A cam like an isky triple 12 will work awesome especially in a 4.8 moving the LSA down to 110 will give it that extra sound you want without sacrificing low end power. It is an extremely efficient cam for small cube turbo applications.
