Good point Mark! I don't ever remember that being brought up in the many discussions, before? You are correct about the flywheel being modified to connect the modified converter for the automatic transmission.

The special engine code and transmission code have had numerous discussions ever since it was discovered the Gibb Novas were built and made possible by the COPO process? Not much to learn in Chevrolet manuals?
