"the car studders" isn't much of an explanation. Feed us with a little more info, and we'll try to help ya out.
What is your base timing set at, what is your fuel pressure, whats your H/C/I combo, etc...

I dont care what your H/C/I package is if your engine is a naturally aspirated 302 you are way over-injected.

hey, maybe its a 9000rpm engine, I was just giving the benefit of the doubt

Or maybe I overlooked the injector size.
I agree, you've got way too much injector. Try turning your fuel pressure down to about 20psi, then it might run
