Mentioned about 1/3 of the way down on this page: http://www.cobra65.org/hardcore99.htm Basically, you balance the crank and flywheel as a unit to eliminate the need for a harmonic balancer. Anyone ever try something like this with a BBB? - Freed
Well, except for the fact that the guy refers to the "flywheel" a hundred times when, in fact, it looks to me like it is really a flex plate, it seems interesting. He does mention that the balancer is left on. Which I think needs to be done to cancel the harmonics caused from the reciprocating assembly. I'm not aware of any modern engine that doesn't have one. Anyone?
