we need to know what kind of heads your running first.
If you have 243 cathedral port heads then run a ls6 intake or a fast 102 the ls6 will lose you some HP on the high side with the cubes of that motor.
if you are running ls3/L92 heads then a ls3 intake would work well or you can upgrade to a 102 on that also
