You're going to have to reset the timing...

To replace the distributor first remove the distributor cap and rotate the engine so the end to the rotor button that contacts the cap is pointing directly at a reference point you will remember and that won't be moved when you remove the distributor. Then remove the hold down clamp and disconnect wires going to the distributor and then remove the distributor. Put the rotor on the new distributor and put it back in the engine, making sure the rotor points to the reference point. The distributor should fall right back in to place. If it doesn't it might possibly be not lining up to the oil pump drive and if so as long as it is meshing with the gear on the cam, bump the engine over slowly with a little pressure pushing down on the distributor and it should fall into place. after that replace the hold down and reconnect the wires. It should be close enough to start and then you will need to recheck the timing using a timing light
