this is a NEW Performance Mini Starter for Ford V8 engine 289-302-351W before 1993. Here is what they says about this: This Ford Style Mini-Starter is an “Upgrade” for most applications prior to or near 1993. At only 8.5lbs (vs. the 18 lbs stock field wound starter in those early years) it often reduces weight almost 50% and requires less cranking amps. In the vehicles where it is a direct replacement there are no changes or modifications needed. Because of it’s very small size it potentially increases header clearance and reduces the effects of “hot start”. This starter works well on higher compression engines and is in use with customers on 12.5:1 compression applicationsOur Part Number: SFD0001 - NEW Ford Mini PMGR Racing Starter 302 351 Higher Torque Fits Most Automatic Transmission Models & Some MT This Ford PMGR 12 Volt, CW, 10-Tooth Pinion starter is 100% New and sold outright with no core charge!Used On: (1996-92) Ford Bronco 4.9L, 5.0L, 5.8L w/ AT (2002-92) Ford E Series 4.2L, 4.9L, 5.0L, 5.8L (1998-92) Ford F Series 4.2L, 4.9L, 5.0L, 5.8L (1991-90) Ford LTD Crown Victoria, Mercury Grand Marquis 5.0L (2003-94) Ford Mustang 3.8L (1995-92) Ford Mustang 5.0L (1997-90) Ford Thunderbird 3.8L, 5.0L (1992-90) Lincoln Mark VII 5.0L (1990) Lincoln Town Car 5.0L (1997-89) Mercury Cougar 3.8L, 5.0L This starter will also replace- (1991-82) Ford Mustangs 5.0L (302 CID) All (1979-68) Ford Mustangs 5.0L (302 CID) w/ AT (1973-69) Ford Mustangs 5.8L (351 CID) w/ AT And others, email us your application This starter will replace older 4 inch and 4-1/2 inch 9 tooth bendix gear starters providing a 50% weight reduction and requiring less cranking amps while cranking with twice the torque!Because the PMGR starter is a smaller size, it provides better header clearance and reduces the effects of a hot start.
