Title: How can I tell if it is a steel flywheel and not cast?
Post by: Qikbbstang on April 12, 2016, 08:10:02 AM

I've got a small collection of new take-off flywheels from a defunct Ford Industrial Distributor and a one I obtained I strongly believe is steel since it came off a serious race motor w/scatter shield.

None of the flywheels have any casting marks, integral counter weights or numbers and look to all be 100% machined making me believe they are steel.

They're all internally balanced FE or 429/460s,


Kind of odd but the brand new steel and alum flywheels I have only have SEMA sticker's that are far from permanent. Maybe stamping IDs into something you don't want to explode is frowned upon?

Most cast flywheels are rough/bumpy in the dished part where the bolts go.  Your billet wheels will be machined there.

Brent I already stated:  "look to all be 100% machined making me believe they are steel."

When I said 100% machined that can be taken to the bank they are MACHINED EVERYWHERE -- not a square 1/4" of anything that looks like a casting.

 So I guess I am more than anything questioning if FoMoCo Industrial and or Ford Motor Co would have produced/included steel flywheels on Marine/Industrial 427s/429s/460s?........................... When I think about it I find it surprising if Ford delivered high rpm 6,000rpm plus motor'd cars with cast wheels...


Anyway to confirm by a layman that they are steel?......

Cast iron melts at 2300°F.  Steel melts at 2500°F.  You can try that.
