482supersnake, what is the application? With a 65 and later starter and 184 tooth ring gear, I have used OE Ford full size starters on my 12.0-1 compression, and my 427 with 11.0-1 compression. Never had an issue, other than a few pounds heavier than a "mini" starter, which is usually based on a Japanese Denso or Hitachi starter, originally designed for a 4 cylinder or V6 engine.
