bendix ?????

I have been told that there are 2 bendix's used for most AMC/Ford type starters ,one has 9 teeth and the other has 10 teeth  ,  my question is witch one is for the V-8 engine ,  I think I may have a wrong starter in my V-8 as when it starts it sounds like an organ grinder.any help please

AMC should be 9 tooth and you have to watch the engagement throw. AMC should be 0.930" - this is from memory so should be checked, some Ford's have only a 0.750" to 0.780" throw and will grind on an AMC every time.

You didn't say if it was a reman, or has been repaired, etc. - if it's an original AMC starter there will be a number in the starter frame. Later ones used a decal with the AMC number on it.
Otherwise, if a reman, chances are it's made of Ford starter parts (meaning starters made for and installed on Fords) with "will fit AMC" type drive and end on it. 

If you have some numbers, I may be able to check as those starters for AMC had specific numbers cast into the drive end (the cast aluminum part)

believe it or not in my 290 4spd I used a 77 Fairmont 6cyl starter and had no issues with grinding I used it because of terminal location and header clearance
