I picked up an aluminum flywheel with no insert. This was from a boat, but i hear these were used on the street too. Should i run it? Any suggestion on flywheel? It'll be in a 1800-2000 lb car.

Otherwise, does anyone have a source for a bolt on insert that bolts thru the pressure plate bolts? I know they made them back in the day. 

I can machine a insert for it, but i dont really want to

If I remember correctly, all quality  aluminum flywheels had a steel facing.  Must be  a reason for that.

I’m running 2 aluminum flywheels from John Mummert. My 55 bird, and the 32 Cabrio with the F code. Both cars are over 2000 lbs. got to slip the clutch a bit on the bird, the 32 just leaves. Great fun thru the gears, revs like it’s headed for heaven. Don’t know about adding a steel facing, but I like the like light wheels.

On mummerts site, it only has steel faced flywheels. Are you sure these are alum or alum with a steel insert?

3000 miles if you baby it.had one pure junk.

I'm not a boat guy but I asked a friend who is and his explanation was a boat can use an all aluminum wheel with no steel insert because there is no clutch pressure plate. There is a cover plate thing ( I forget the name ) that connects then engine to an output shaft, it's a solid connection ( it's a direct drive ) so there is no slippage or shifting like a car. He highly recommends not using it in a car as that is not it was designed for..

Sorry, the way I said that was misleading. They are aluminum flywheels, and they do have a steel facing for the clutch disc. I’ve been using aluminum flywheels for 50 years, all had the steel facing.

Just thought Id throw in my 2 cents, though I've never personally had  an aluminum flywheel.  First, aluminum is way softer than steel, so wear would be a factor. Second, the melting point might be a factor, especially if the clutch got hot.  The disc would end up looking like some of the grinding wheels I've used on aluminum and probably work about as well as those wheels after they were packed up with metal.
