Got the 572 back, Now lets find some power

You didn't include that the engine mentioned was on E85. 12-1 on E 85 is about 15-1 on gas. That's super lean. A gas engine will be pig rich at 10-1

and thats what i thought also....

Yeah if the wideband was on an E85 scale even 10-1 is super lean as 9.68 is stoich. I would start targeting wot a/f around 8.5-1
 
Update, The cars is running great, Zero vibration even on a solid motor plate. Don't even realize its solid mounted. The Holley 4500 TBI is fantastic and very tunable. I have a beautiful Fuel Map that I have been working on and only see about 1-2% correction at any point. I can reach my hand in the window and it fires up without touching the pedal at any temperature. Makes great power. Working on keeping the car in the lane when I stand on it. Seems to want to drift left and cross centerline if not counter steering. Not an immediately goes left type thing, more of a slow drift over. Think I need to preload left CalTrac bar. Car is point and shoot type deal. Straight road and wheels straight. Sometimes scarry....I do have a pretty aggressive Pop/Back fire in the header during 1-2 shift if getting on the limiter @ 7400. Can't seem to tune that out. The 1-2 shift happens extremely fast almost no time to go from trans bake to shifter in time. It does have a low gear kit in the trans, I'm not sure I really like. A shift solenoid whether Air/Electric or CO2 would be best but its a reverse pattern so that's a problem.
