THANK YOU!

I was about to write that. Late ‘72 340’s were externally balanced. Not the whole year. I have not actually ever come across a external balanced “‘72” 340 engine. They have been all internally balanced.

Thats why I wrote on page to Generally '72's are cast and all '73's are. :D See, Im learning little by little as I go along. :P

The 340 I sold last year to make ends meet. :( Was a Cast crank '72 340.
