Yes I know the generally accepted balancing formula for V8s. Take 40 grams off the piston/pin and the 20 grams goes away, IF the extra weight is concentrated at the big end. If it's the result of a slightly heavier than stock rod beam then it'll be less than 20 grams. Lightening the rod journal would be my fix, like Chrysler did on the 340.
Suggesting someone will need Mallory because of an extra 20 grams in connecting rod weight is pure and simple "putting up a straw man to knock it down". That doesn't fly at the debate club and not here, either.

Aren't you an engineering professor? A data driven field where ASSumptions can yield catastrophic results?
How do you know what bobweight his current crank was balanced at?
Yes the rod is 20 grams heavier total, it also has a .104 smaller wrist pin bore, who is to say the rod is not 85 grams heavier than a stock rod on the big end?
My point is no one in this thread has the data to determine if the crank will balance out fine or need mallory and no need to call in the debate team
