Chrysler starter spin down time

Al Bundy said

Hi,I replaced the starter on my 70 Dart yesterday with a rebuilt factory Chrysler gear reduction unit. it had a Denso one on it previously that finally went out so I wanted an original Mopar unit to get that old Mopar sound back. The starter works fine,but I've noticed the spin down time seems like 4-5 seconds after you let off the key. Why do these spin so long?

When properly built, they don't—that's only when they're worn out or when thrown together by a "remanufacturer". Way-too-aggressive blast-media cleaning of castings, failure to use the correct leather brake washer (and install it dry and make sure it stays dry), misapplication of way-too-big so-called "high torque" field coils, and all the rest of the don't-give-a-futz procedures that go into "remanufacturing" starters all add up to a starter that sounds like hell and takes forever to spin down (and has a short, unhappy life).

Don't believe me? Listen and hear for yourself; Here and here are recordings of a properly-built large-frame (1.8hp) Chrysler gear-reduction starter cranking and starting my '62. And here's a properly-built small-frame, 3-series/1-shunt (1.3hp) Chrysler gear-reduction starter cranking and starting a 440 in a '66.

Want back that classic Chrysler "Highland Park Hummingbird" cranking sound, without the hair-raising gear thrash and long spindown? Have an original starter built up correctly, or buy a new old stock unit (they are not difficult or costly to get hold of; I have more of them on my shelf than I'll ever use.)
