Balanced Crankshaft (Need Help !!!)
'73 340's are externally balanced. If someone put a forged crank in it, it would be internally balanced and you would not want to run the weighted balancer or flexplate.
What is the number on your crank?
If it balances out OK then that is fine but, he is giving conflicting info. First you say he said it was an internal balanced crankshaft, then you say he said it is better without the weighted flexplate but still needs the weighted balancer.
Boy, I don't know want to think.
