Hey guys need some help! Does anyone know of or how to tune a Holley Truck Avenger. Its a 770 cfm on a 454 bbc I am willing to take it to a shop if you know of one or pay you personally (cash or beer) if you can help me get this thing running right or closer to right.

454 bbc
comp cams mild off road cam
holley blue electric fuel pump

Problem: It falls on its face when you stomp on it but runs fine with a smooth acceleration or stable throttle.

Can't offer much help other than to say I tried Carbco on the southside and all I got back was cleaned and painted carb. Didn't run any better than when I took it there $200 earlier.

sound like you need to change the accelator pump.
