Clearly, shrink on weights will weigh more than the weld on ones because they go all the way around the crank flange without adding any more counterweight effect. I don't think we have enough information to properly answer this question.

Using steel weights, about the maximum you can cram into the space available is 65%. By lightening the reciprocating assembly to a minimum safe value and using tungsten or depleted uranium for weights you could probably get very close to optimum. HOWEVER, I can tell you from first hand experience, an engine built this way is a horrible slug on a circle track.
It would do well in parades.
