Didn't Buick use the same part when they installed automatics?

Art, I may have one.

Curtis and all :Olds used cast flywheel. 215" Buick used sheet steel, for 5 element Dual Path torque convertor.

Did not know that about the Olds.  My Buick 215 flexplate that I no longer have was definitely not cast.

The flywheel needs to match the trans, not the engine. The Buick two speed AT used a torque converter and a conventional flexplate. The Olds Rotohydramatic 5 used an internal fluid coupling. Without the rotational mass of a torque converter on the back of the crank, the Olds 215 needed a heavy flywheel, even with an AT. The AT flywheel has a spring-loaded damper plate that looks like the center of a clutch disc. The trans has what looks like an MT input shaft that fits into it. The bellhousing on the RH5 trans case is smaller as a result. If you put an RH5 behind a Buick motor, you need the Olds flywheel, and vice-versa for putting a Buick trans on the Olds motor.

OK. I used to have 2 of those. Used them for feet on the leveling jacks on our old RV. Long gone.

Take out the torsional hub and they're lighter than a steel, stick flywheel.
