Trying to see just how different they are with respect to lobe placement, I think the ends and the gear is the same.

Someone once told me they used a Leinwebber J-3? cam in a similar motor and it ran ok, but I never compared to a stock knuck cam. The shovel cylinders will not bolt up to the knuck heads. You can used untimed crankcase vacuum to return top oil but it helps to have a pcv type one way valve in the line. You can use a fitting in the timing plug hole as S&S did with their prototype sidewinder motors or tap in above the crancase oil return trough at the top of the rear motormount. A board member, wawilhelmo, or something like that, has built a shovel bottom with knuck top bike. You may want to look him up in the member list and see if he will help you out.
