340 Crankshaft balancing.

I tend to agree with Tony-if the engine will be rebuilt anyway, there's nothing wrong with a cast crank as long as the correct balancer and flywheel are used. There's nothing "crazy" about a counterweighted balancer...360s use them with no ill effects. Of course it's preferable by many to use a zero balance setup, and I can't really dispute that, but as mentioned, unless a good 340 steel crank can be bought for the same cost as an appropriate balancer and flywheel (which will need to be bought anyway for his conversion from auto to 4 speed) then buying one would be all but frivolous, no?
