340 w/ 650 double pumper ?

I've had a 700 DP and a 650 DP on my low compression 340, with edelbrock air gap, super sucker 4 hole spacer, headers, unknown aftermarket cam, electronic ignition, Automatic transmission.
The 700DP pulled a bit harder on the top end, but the 650 was a little more friendly on the gas. Both of them had no problem idling and cruising around town. Never had any flooding problems.
