ok people, i'm putting a 5.0L in place of my 65 289, how can i tell by looking at a balncer if it is a 50Oz. or 28? i have a bunch of balancers, some are older but bigger like the one that came on this 5.0L, does that mean anything? The reason I ask is because I have to come up with a 50oz. for the new engine that puts my v belts where I want them. Anyone have knowledge on this? Thanks
