    There are many answers to this subject.
    What is your budget? Engine capacity, cam profile, expected horsepower, etc?
    A 4160 is Holley's cheaper alternative to a 4150, since only the primary side has a metering block with replaceable main jetting. The secondary side of a 4160, has a metering plate. The secondary side of a 4150 resembles the primary side, so both sides have a metering block. If you expect to change jetting often, then a 4150 is the way to go. Gary
