Why is it everyone who is down on the 400 for being externally balanced (as opposed to having siamesed bores so it doesn't cool as well) in the same sentence says "make a 383 instead since they make so much torque"? The 383 is externally balanced too, since it is made using the externally balanced 400 crank. As a corollary to this, do any aftermarket manufacturers make stroker cranks for the 350? As I understand it, in order to use the 400 crank, the mains have to be turned down some ungodly amount. I would think there would be a pretty good market for a long-throw internally balanced crank for the 350, so you could get the stroker torque advantage without dealing with external balancers or way-undersized mains. Any help on this one?
