Having starter/ring gear issues with a new build on a 1973 460 Ford. The bell housing, clutch, p.p. and flywheel were on the previous 460 that went terminal. I purchased the car (69 Fairlane) with the engine already installed (supposedly less than 1k miles and the clutch looks new). The person I purchased from did not do the install and doesn’t know the origin of the parts. The flywheel has 184 teeth (427?). The starter is a Summit Racing® Protorque Starter SUM-820048. The clutch and p.p. are Luk. The engine started several times on the test stand and about 5 or 6 times after getting it in the car. Then it began to grind and just spin. I had failed to check the flywheel closely before installing it on the new build so it’s my bad: Found the starter teeth only engage about an eighth inch into the ring and only about a third of the way across the teeth and both the gear and the ring are damaged. When the starter is off the engine it kicks the gear out plenty far enough to fully engage but it appears either the tooth count and/or pitch are wrong. It appears the problem existed on the previous motor because the block plate has been cut off to allow the starter to bolt directly against the block (another indicator I was too dumb to see when I put it together). I guess I’m looking at the results of someone converting an automatic to a 4 speed and not getting it right but don’t know enough to correct it. I’ve read several posts about starter issues on 460s but I didn’t get a clear idea on what to do. Any help would be appreciated.
