Re: Noise on my 70 with new muncie
Didn't read all the replies, but, some things to think about..
Gene is right on with the flywheel.
If that is true, it could be bad news.
My engine builder balanced the rotating mass together.
That means the crank, rods, pistons and flywheel and harmonic balancer. He did drill the flywheel some.
its the pressure plate out of balance, which is a long shot,
or the bushing in the end of the crank for the trans pilot shaft is missing or the wrong size.
If the flywheel was not bolted squarely with the crank flange, it would vibrate like crazy.
If the pressure plate were not fitting flat on the flywheel, it would vibrate like crazy.
If the bushing in the end of the tail stock for the drive shaft were wrong, worn out or missing, it would allow the driveshaft to run out.
Check your tranny mount for excessive play. you should have put a new one in there.
Do you have the wrong harmonic balancer on there?
When you find the problem, please post the solution.
