spooky holley 3310c

I am about to go crazy with this holley. its a 3310c 750 street strip carb. i have it set to where the engine will idle. the motor is a 355 small block chevy, aluminum heads weiand single plane intake 10.5.1 comp, 550 hyd flat tappet cam, roller tip rockers. Idle is at 1300rpm. at first i had trouble with a bad hesitation when throtle was opened fast. finally figured that one out. pump cam was on backwards. now it will rev while in neutral with no hesitation. put it in gear build to 2000 or better with brake on hit the gas and it falls flat on its face. i am 62 yrs old and could out run it on foot for 60ft. its bad. doe anyone have a clue as to what may be wrong now. bottom of accelerator pump stays a little damp with gas. it is set at thousands and is real loose at idle.
when in neutral it has no hesitation and engine will hit 5000rpm in a heart beat but when in gear will barely pull itself.
like i said this is a spooky holley.
