0-80770 : Street Avenger, 770 cfm, Square Bore, 4-Barrel, Vacuum, Electric Choke, Dual Inlet, Silver
HR-780-VS : Carburetor, HR-Series, Gasoline, 780 cfm, 4-Barrel, Square Bore, Vacuum Secondaries, Electric Choke
Both the Holley and the Quick Fuel carb cost about $400, but the Quick Fuel seems to have several more features
that the Holley does not have.
Holley
Only primary or two corner A/F idle adjustment.
Have to change spring on secondaries to adjust opening timing.
Quick Fuel
Aluminum float bowls.
Screw in air bleeds.
4 corner A/F idle adjustment.
Sight glass for fuel level adjustment.
Quickset external secondary timing adjustment.
If all the features of the Quick Fuel work as advertised, then it would seem that this is an easy
decision. Does anyone have any input or can point me to a review of the QF carb ???
