I have 1977 cutlass with a 403cu./350 AT. I see a GM distributor for sale part# 1103320. It is listed for a 260cu V8 Olds. Would it work on my application or would the vacuum curve be wrong for a 403cu.? Could I just drop it in or what would I need to do to make it work? I have an existing distributor in good shape.

Thanks
Mike
