This a used Ford 302/5.0 engine Bosch remanufactured starter motor. Motor was bench tested and showed it still has life. This can be used to replace the large starter motor on older Ford products. It was taken off and engine with less than 750 miles.
I've purchased Bosch starters in the past around the same price. I spend the extra money because I live in Mn and our winters get cold and I need the extra cranking power for cold starts. This particular starter did nothing more than my cheap o Reilly auto Parts starter. Cranking Amps is what you are looking for and this one at roughly 3.5 amps just didn't have any extra power. The other Bosch starters would turn my truck over instantly no hesitation ever till the day it went out completely. I purchased the good one from Bosch for 250$ that's with core no core return. So look around be sure you are getting what you pay for... cheers
