Look at an Aftermarket balancer...such as Professional Product 90012, it comes with 3 bolt on weights...

one weight for cast crank externally balanced 340

one weight for cast crank externally balanced LA 360s 71-92

one weight for cast crank externally balanced magnum 360

and the balancer can be used with no weights for a internally balanced 318/340...

dont see a different weight for a 70s 360 nor a different weight for a 80s 360...

So Albert Einstein would concluded that one weight would fit all 360s from 71-92...which is weighted the same as OEM balancers from 71-92....
