Points are located inside the distributor. You probably do not have points ignition. You probably have electronic ignition (HEI) with the big distributor cap that is almost bigger than your hand.
If you did not put the distributor back in with the rotor pointing in the exact same position as it was, you will need to get the engine set on top dead center(TDC), which is just after the #1 cylinder (driver's side front) intake valve is closed (note: the front most valve is an exhaust valve) and the timing mark comes aroung to zero. (rotate the engine clockwise, and DO NOT rotate the other way if you go past TDC, because a worn timing chain has slack and this may cause you to be as much as 20 degrees of timing off). Another easy way to find TDC is to remove the #1 plug and turn the engine over until you feel the pressure of the cyclinder pushing on your finger, then after it hisses at you, turn the crank until the timing mark comes up to zero. Now pull the cap off the distributor and make sure that the rotor is pointing at the #1 plug wire. You can either pull the dist out and re-install with the rotor physically pointing at #1 cylinder (like most people do, but is not required), or you can just move the spark plug wires around the cap so that #1 and the rotor are matched. You will have to look up the firing order on your intake manifold or someone else may be able to provide that.
