This special 3 bolt 50 oz crankshaft damper is used on late model 302 engines from 1981-up with
50 oz. balance. It has 3 bolt lower pulley holes with timing marks on both sides,
allowing use in 1961-up cars with old 289/302 pulleys.
They are used when installing a late model Ford crate motor using a 1981 and up 302 block into a vintage 1962 to 1972 vehicle
using a 3 bolt lower pulley.
This is important because it allows you to save a lot of time and money by using your current 3 bolt crank pulley and front accessories and brackets and not have to buy all new parts for the front of your
engine.
