No Mallory required. Balance the crank all by itself or with damper and/or flywheel but no bobweights like you need for a v8.
Interesting. I asked this on a different forum and was told that it needed bobweights. if you are truely making the crank neutral balance than you would be able to swap rod/piston sets (assuming each rod/piston in a set is the same mass)without rebalancing the crank. Thus you can change rod length and piston height at will, using the same crank?
If so, this would save a lot of $$ and time when trying out several combinations.
