Holley 600 cfm 4-bbl Carburetors
Holley has developed these carburetors for the budget minded enthusiasts. All carburetors are 100% wet-flow tested and calibrated for use on stock to mildly modified engines. These carburetors have vacuum secondaries which are for use on a wide variety of vehicles. Vacuum secondaries compensate for all vehicle weights, gearing and transmissions to allow for smooth opening of the secondaries. Carburetors are available with either a polished finish for show-quality looks or a dichromate finish for excellent corrosion resistance.
