5.9 Magnum flywheel - DIY with bolt-on weight??
I think there's a diagram with the weight removal (drilling) of a neutral balance flywheel. You would probably need a machine shop to do it for you. I went with the MP flywheel for my 360 magnum with a viper T56 tranny. My clutch is a 10.5 mcleod unit for a camaro and works perfectly.
