few questions about 302 5.0 installation

The timing cover you select is based on whether you wish to use serpentine accessories or v-belt accessories. If you choose serpentine then you use the late cover, electric fuel pump, late harmonic (see below), reverse rotation water pump. Optionally you can use the factory crank trigger and electronic ignition system. If you choose v-belt then you use the early cover, fuel pump eccentric, fuel pump, early harmonic (see below), normal rotation water pump, distributor ignition (electronic or points).

Harmonic balancer. The selection of harmonic balancer depends on the crankshaft you use. If you use early then it needs to be a 28 oz-in imbalance harmonic and if you use late then it needs to be a 50 oz-in imbalance harmonic. In addition, the harmonic must be drilled and configured for the pulley system you use. If you narrow down what you want to do, then my advice can get more specific. Right now, I'm not sure where you are going with your project.
