I went with a new edelbrock 3 years ago and never looked back

cthulhu - so when running a speed demon you need an upgraded fuel pump? I've got a road 625 I haven't installed yet. If so, please let me know what type of pump you rec.

Thanx

if you want mileage and decent performance go spread bore/q-jet, if you want to lay 50 ft black marks behind your car... dont go q-jet. to be honest the difference in a 650 rochester, holley, demon or edelbrock with vac secondaries is actually rather trivial if anything at all from a performance standpoint.

I'm not sure what you mean, if there's not much of a difference.
