 FEAR NOT THE HOLLEY
A new release from the Superior Automotive Video Library,
Rebuilding the Holley Carb, takes the fear out of reconditioning
and modifying the Holley 3310, 4160, and 4150 series four-barrel
carburetors. Accompanied by easy-to-understand narration,
this 30-minute video takes viewers through a typical rebuild
where the smaller details are explained via close-up shots.
Numerous performance modifications are made to the example
Holley 4150, including air-horn removal, milling the carb
body for enhanced metering-block gasket seal, drilling the
primary butterflies for smoother idle with wild cams, installing
a metering-block vent baffle, idle feed-restriction hole enlargement,
beveling the jet orifices, installing secondary jet extensions,
replacing the secondary metering plate with a metering block,
and more. To prove the value of the modifications, the 4150
is bolted onto a big-block Camaro and tested on a Dynojet
chassis dyno where it produces an additional 23 horsepower.
