just put in a new starter on the 454 and it grinds the flywheel, got the starter at autozone they said all their 454 starters have same 9 tooth bendix, and they work with both flywheels, the flywheel ring gear and teeth look fine. hopefully some more experienced guy on here can help out. Thanks

Did you get shims with the starter?, lot of those rebuilds especially from the Zone has the mounting pad surfaced and ends up being too close to the flexplate and that will make it groan that's why they give you shims. These instructions should help to get the right clearance for your starter.

Also 454 uses a different flex plate than a SBC. The starter you have should have the bolts on a diagonal like this orange one, not across from each other like the black one:



You can swap the ends (as all GM parts interchange if humanly possible) but the diagonal starter pattern generally signifies a 168 tooth starter ring found on an 11 clutch and fly wheel used on all big blocks and high performance small blocks. The smaller 153 tooth starter ring is used on the base SBC and L6 motors works with the smaller 10-1/2 inch clutch and flywheels.

The other distinction is whether it is a high torque starter motor that is spotted by the power lug positioned a half inch in front of the solenoid.



versus the power lug being tucked up next to the solenoid on the standard 153 tooth starter motor for sixes and base V8's.



As Art has mentioned unless it is a new GM part odds are it will need to be shimmed to get the required clearance (you can use a medium paper clip if you don't have the wire gauge to set clearance)
