Default Car hesitating...

ok, got the car running and driving... thing is now it seems like when I start to get on the gas, like any, not pedal slamming, it kinda hesitates before going, almost like its going to die out, then catches itself.... any ideas ?

Check the TPS for a dead spot with a meter.

Your first post says "got the car running and driving".......... Had it been sitting long? What was wrong with it before?

I had a 68 Camaro with a Ram Jet 350 and it did the same thing. I'm sorry to say I never did get it figured out to my liking even after two trips for a dyno tune by Arizona Speed & Marine. It always stuttered right off idle. It was a brand new crate engine. Checked everything and ASM did as well. I hated that engine. I wish you infinitely more luck getting your straightened out. Sorry I'm not much help.
