is there any thing different between them??besides one being square tooth and one being round. is the round one make less noise??less firction?? i noticed it on a 93 2.3 stang at the JY.
round tooth supposedly holds better without slipping, a few of the higher hp guys had problems with slipping on the square tooth, they switched to round tooth and stopped having problems.
i had it in neutral and i revved it hard and it jumped a tooth... not very impressive when you rev on someone and when you go to take off your cam timing is a tooth off and you sound like an old jalopy pulling off the line... LOL.
