Joe and group,
The thing to remember about the flex plate is that it is designed to be mated to a big fluid coupling. That GREATLY lessens the shock loads on the flex plate. Using it directly bolted to the drive allows all kinds of different vibration loads and torsional loads it may not have been designed for.

I have been looking at various flywheels for possible candidate replacement.

I thought the aluminum units would provide the least amount of weight gain.

I noticed that there are a lot of holes in these units including the replaceable friction area with many screw holes.

I was under the impresion that the holes in the flexplate promoted stress cracks.

These flywheels however may have sufficient material to counteract the stress potential.

Can someone provide a brand or part number that is acceptable?

I believe that the additional machining to modify one of these flywheels is the holes for the torsional damper.

Thanks for any help.
