if the DOD is in the lifters, y would changing the cam affect it? should still work no matter what cam was in there, as long as the lift was less than .590", right?
and the LS2 cam and heads r the same as the '01 LS6 cam and heads... so the LS4 heads r the same as those except with the old LS1 valve springs...

The crank is the only thing diff, Heads are 243 LS6 and any LSX cam should work! Don't get intimidated because it's sideways, it's mostly the same just tighter constraints! 
If GM doesn't come out with a nicer 4DR "SS" within the next 2-4yrs, I will pull this baby out, stroke it (383-408) and have the trans done by Eric@ DynoTech! Not a drag racer, just a 450HP cruiser that will go from 60-150mph with the best of 'em! Hmmm??? M5, E63, you get the picture! I'm kinda surprised we haven't seen that yet? Anyway's wish I had the ***** to put a cam in it now! 1400miles!I gotta wait!

This isn't too bad, it all comes down together then it's simple, those 4th gen f-bodies aren't much easier(valve springs)!

Comp Cams makes camshafts for the 5.3 DoD engine. I know because I've called them. The only concern is the bolt pattern on front of the camshaft. The factory cam is likely the single bolt version whereas most cams made are still the three-bolt versions. Lingenfelter make an adapter for this.

Youtube: Type "Sound Off GXP Mustang", first video, kinda dark, both cars *** ends.. That's a cammed LS4, using the New Era G8GT High Lift DoD cam.. I don't see why aftermarket cams for the LS1/2/6 won't all fit?
