The distributor problem concerning oil pressure with the 265 was resolved in the late 1950s with a different shape to the housing where it intersects the oil passages to the valve lifter oil galleries. The original 265 distributor had a flat spot which had to be clocked exactly right to allow oil to get to the passenger's side lifters. If the housing was rotated incorrectly and the spark plug wires repositioned to compensate, half the lifters would lose oil pressure and collapse, while the rest of the engine would get lubed properly. Any distributor from 1959 forward will solve the problem, because it has a full circle groove instead of a flat spot in that area.
