It can be made to work, and now that the search is working a little bit better, said search will yield some results. Items needing to be changed to run the LS2 or LS7 cam will be front cover, LS2 style timing set, cam sensor extension harness, and plug rear cam sensor hole.
That LS7 cam is HUGE for a 5.3L motor! What stall, gear, supporting mods, etc do you have? What ar your plans for the truck? All race, all street, a mix, etc?
I have a 02 camaro 6 speed trans. i want to make this a fun street truck. i was wanting to put a z06 cam in it and i found one on corvette forum out of an LS7. I know i plan on doing a better cam and hard valve springs. Any recomendations?
You can make the LS7 cam fit, but the very high intake centerline and very late intake valve closing point would put the dynamic compression in a small 5.3L into the toilet. You would actually go slower with the LS7 cam in a 5.3L truck. Obviously, there are much better choices for the 5.3L, but I don't think the LS7 cam is one of them.

It's a 210/230 .561/.558 120LSA w/ 1.7 rockers. There is a lot of split to compensate for the "poor" flow of the exhaust ports and manifolds of the LS7. I'd go with a cam more custom tailored to a 5.3L or go with a LS6 Z06 cam.
