"When the truck is in natural and the clutch in-gauged both in gear and in neutral and it still had vibration would this eliminate the clutch plate ?"


If the disc is complete and no twist evident I would think it would be fine. The clutch cover/pressure plate would be more suspect as it rotates with the crank all the time.


I did find another old post flywheel picture on the net. A lot more knowledge on this site also.


Balancing looks different for sure........

Might be worth having the flywheel checked for neutral balance.

 

I was told there are 2 diferent cranks for the 318. 1 internal balance and 1 external balance. 1 cast and 1 forged.
If I'm wrong please tell me. I mostly have Fords untill I bought my 75 W300.

 

You could look for a 360 also if your not opposed to more cubic inches.
