Installing the new distributor on the 360 requires some finesse because the DUI distributor has a larger body and it can be a tight fit, but not impossible. Fuel lines and the power steering pump all want to occupy the same location as the new distributor cap, wiring, and vacuum advance. Once you find the optimal location for the vacuum advance you’ll also want to get the rotor to point close to the mark you have on the engine for No. 1. This may mean trying different distributor gear to cam gear orientation or using a long screwdriver to rotate the oil pump so the distributor falls into the desired location completely.
