a Windsor gear is 1.249" or just about 1 1/4"
a Cleveland gear is 1.421" or between 1 3/8" and 1 1/2"
the gear needs to be installed VERY correctly or you can destroy the gear on the cam

well it had an aftermarket cam and i wentback to stock when i rebuilt the motor. i tried a distributor from a 351w and it wasa no go. 351m and 400 have same part number for cam and distributor. the distributor slades all the way down into place, but the teeth dont catch, so what should i try do you guys think? get a 351m/400 distributor and swap the gear? what do i swap it to?

no because my module went bad so i changed my distributor. so about a ile down the road it backfired and stopped. so i went back to my house and it wore the teeth off the distributor AND the cam. so i got a stock camshaft and installed it. i got a 400 distributor and went to put it in. i can feel it go all the way in. it sits in place but i can still spin the rotor 360 degrees around.

maybe measure the gear? and notice if the roll pin that holds it in place on the shaft is there and intact... the pin can shear internally and still look like it's OK but sometimes it's not. if it's a new/rebuilt dizzy i'd expect that it's OK but ya never know
