302 balance problem
Your flywheel can cause problems, but what is the motor doing. If it is "waivering" vibration then it is more likely to be a bad "Harmonic Balancer". If so, grab the outer ring of balancer and try to move back and forth, if any movement by a new one immediatly before you do end up with crank problems. Summit and Jegs sells good replacements (I always got improper balance with Ford OEM balancers when the engines were changed from stock). My motor started vibrating slightly, then got worse, then I thought my fenders were going to fall off, changed harmonic balancer (not flywheel), now runs like a 40 year old kitten, but is mean with my foot in the carburetor. Good luck. I don't know how to work this site yet. I can't find my own question.
