SBC lopy idle

I'm running a stock sbc, stock cam, heads etc. with a three duece intake running three rebuilt holley 94's. New fuel tank, electric fuel pump, fuel pressure regulator. New plugs, wires and rebuilt distributor.

The motor has a real lopy idle, and bogs down if I hammer the gas. Any ideas what the problem could be?? Thanks guys.

 

Could be anything from a bad carb, low vacuum, timing too retarded.

 

keep pressure down to 2 lbs so it wont flood
