I'm no expert, but I believe you would need a degree wheel and dial indicator to determine the best setting. Setting it to 0 should get you running, that's probably what id do unless there is no rush to get it going.

Like I said, I would think you would need to verify whether the cam was ground for a 302 firing order, or a 302HO/351 firing order....just to make sure.
Other thank that, just make sure your distributor was installed right. #1 piston TDC on compression stroke, and the rotor pointing at the #1 post. That'll get you in the ballpark.

Look closely at the crank gear, you'll see the "dot" straight up. The cam gear has it straight down. They line up.
Compression stroke at TDC is correct.
Here are some more pics:

Slots...are you talking about the keyways?
Anyone else reading this thread know what he's dealing with?

Ok, I just found this. Look at the keyways, they'll be cut differently. You need to use the keyway that pertains to the "dot" it was cut for. See here:

Then, install the distributor correctly. #1 piston 16° BTDC on compression, rotor pointing at the #1 post.
You know where to go from there.
Do a proper cam break-in. You DID install new lifters, right?

The PO may have used a timing set with a "Multi-index" crank sprocket. A Multi-index crank sprocket like you are describing will have, most commonly, three keyways for the crank key. One will be straight up at 0 degrees, one will be 4 degrees advanced and the other will be 4 degrees retarded. This is so the engine builder can fine tune the power band of the camshaft he is installing.
You probably want the 0 degree slot. It should be marked in some way.
