Here at last from Holley are the new and improved 4160 model 4-barrel carburetor. This carburetor is equipped with Holley's all-new Tru-Set needle and seats, which have eliminated the need for external adjustments. This change allows for easier "Bolt on and Go" performance. The floats have been factory-set for optimum fuel levels at 3 to 6 psi of fuel pressure, and should never need adjustment. If running over 6 psi of fuel, a fuel regulator is required. This carburetor also includes a new, refined appearance on their float bowls, main bodies, and vacuum secondary caps. This carb is the perfect upgrade for any ride.
