Distributor Cap 101

No neither. You did not say if everything is already in place on the engine. If so, follow the #1 plug wire to the cap, and that should be #1. If not, you have to find TDC and rotate the Distributor drive gear in so it lines up with the front left intake manifold bolt. That aligns the rotor straight ahead and at #1. There are books that can show you the process.
