alright, I know that there is a lot of talk about starters on here and I have learned a lot. replacing starter drives is one of the things Im glad Ive learned cause I have to replace one ever 3 or 4 days. I am using the correct starter, the correct flywheel that is in good shape, I am setting it up correctly with 1/8" clearance between the shaft and the flywheel. its a mild 350 with an sm465. Ive broke whole housings and was told that it was because of fast timing. slowed the timing and that quit but then it started breaking the starter drives. I was told it was because of my cam but I have never heard of such a thing. can anyone tell me why my truck keeps eating starters? in the mean time, thank god for lifetime warranties and thank you guys for all your help.
