I'm running a 650 vac holley on my *ahem* 454 for the time being. When ever I get spirited with the go pedal, the carb floods out majorly (Fuel seeping out of the throttle shafts.). Any clues?

Float level?
fuel pump/pressure? (We re-used the factory pump when We installed it. The car it came out of had a return line to the tank, my truck didn't, and I'm not sure how my uncle routed the return line.)

Any help would be great!. (now I must make a sacrifice at the alter of the Blue Oval... ).

EIther the float level is high or the needles and seats are wrong/weak.
Did you replace them?

The carb was rebuilt two years ago.

How about this. I plan on getting a new carb in the next week or so. The local shop (where I get my Chevy parts , Sallee Chevrolet.) recommended the Street Avenger 770cfm (he has it for $289. Thats his "Sale" price (my Dad grew up with the Owner..).

What would you recommend?.

Wow. The 770 Is quite an Improvement.

Only thing bugging me now is the Fuel pressure, It fluctuates between 7-10psi at idle (5-7 is recommended.). At fast Idle, the needle bounces from peg to peg.
