good thread
Thanks
What i don't know for sure and can't get anyone to agree or disagree is......Is the 340 cast crank internal or external balance.
You know, it don't really matter. if you're going to us a 340 crank (cast or forged!) you will need to balance the assembly, because the 318 counterweights and pistons are lighter.
So to the Op. If you don't want to balance your rotating assembly, you need a 318 crank!
