Well I talked to my local machine shop about balancing my flywheel to my pressure plate. Its the last thing left to find where my vibration is coming from. I bought the car with a 306 and h/c/i on it already. And it had horrible vibration through the shifter. So I put in a romac balancer, flywheel from my 95gt, new clutch, new tob, new pilot bearing and rms. And indexed the bellhousing. The car doesn't vibrate as bad under wot anymore. Vibration starts around 4500 rpm and up in gear. And 3500 and up in neutral. But it is worse in neutral. Its rpm related not mph related either.
When I looked at the old balancer and flywheel I found some interesting stuff. It looks like the motor was balanced via drilling material out of the flywheel. Does anyone else have 1/4 inch diameter holes drilled into the flywheel. They dont go through but I imagine they are for balancing. There is one drilled into the balancer about 3mm deep and 4 seperate ones in the flywheel drilled almost all the way through. Im trying to sort out the imbalance somewhere. Anyone have any ideas.
FWIW. The bellhousing was .033 off and there were only 2 dowels holding the clutch in before swapping my tko in. Ive done everything I can so far to try and get rid of the vibration. Any ideas would be great.
