Man you sure love that magic ball.

Back on topic though, trying to balance a 122 tooth flywheel to a 5.9 Magnum/hold the power with a 9.5/10 inch clutch may be an issue. I know they sell "bolt on" weights for the bigger 130 for a 5.9, so I'll probably have to just go that route. Or use just use a 5.2 for the neutral balance aspect. Options, options..
