Thanks for that info on the balance of the flywheel. I'm running a ZF 5 spd behind my 6.9 and will keep on using it but this engine does have the flexplate for an automatic. Do you know if my 6.9 flywheel will work? It's a single mass flywheel and I'm running a custom made ceramic puck clutch,basically the same disc that's used in the 430HP corvette with a ZF center
