My new that needs help!!!!!!!!!!
You have an LQ4 your rebuilding and want to put on "LS3" heads and a cam for street driving?
Assuming that's what your asking... LS3 heads would work nicely on a 6.0L. Cam is totally dependent on what your needs and wants are. The FAST 92mm is a great idea, the powerglide is unnecessary for the street. The 4L60E is a great overdrive transmission for this power range.
