BB CHEVY GEAR DRIVE W/FUEL PUMP DRIVE
Allows precise camshaft degreeing using Milodon's adjustable bolt pattern cam gear and hub assembly.
Incorporates a full cast aluminum front cover with a removable cam cover that allows quick and easy access to the cam gear for adjustments and cam removal.
Mounts the fixed idler gear solidly into the main cover itself. This fixed idler system will fully compensate for any crank position, even if the block has been severely align bored, without any sacrifices.
Uses positive cam end play adjustment and a three-piece roller bearing behind the cam gear to control cam movement, reduce power-robbing drag and stop block face wear.
NO block machining is required. Hand tools are required to drill and ream the positioning dowel pin hole which, with care, can be done at home.
Available in the standard "flat cover" configuration which uses a stock style water pump or the "injected / blown with fuel pump drive" style that does not use a stock-style water pump. Blown engines will require a fuel pump extension (see that section for a complete listing).
For Small Block Chevys, stock factory and Milodon short pumps fit over the 12000 drive with the hardware provided. Big Block short water pumps will not fit over the 12600 drive without additional spacing.
