CVF Racing's polished V-belt system gives a Ford FE engine (390, 427 or 428) the brackets and pulleys to run an alternator, a Saginaw power steering pump and air conditioning. The alternator sits mid-height on the passenger side and the Sanden 508 compressor mounts high on the driver side.
A 3-groove high flow water pump pulley and 3-groove crank pulley drive the system. The power steering pulley is offered for either a 5/8 in. keyway shaft or a 3/4 in. press fit shaft.
