To time it, blykins is almost correct but you want to add in about 10-12 deg. of advance.

I un-corked plug #1, and using a breaker bar with the proper socket to turn the crankshaft at the dampener pulley, you turn the engine clockwise while you have a thumb covering the #1 cylinder plug hole. Once you feel /release pressure under the thumb, you know for sure you're on the compressions stroke.

Now take a long pencil and slip it down the hole. Continue turning the crank clockwise until you see it stop it's upward progress. Note your pointer; you want to adjust it to Zero. Check your rotor and it shoud be right under the #1 spark plug wire too. If not, loosen the dizzy's lock down and move it to that position. Use a grease pen and mark the housing of the distributor where it lines up with the rotor.

At this point your engine is now at TDC, distributor is at 0 deg. advance. Your pointer is now poinitng at Zero.

To go 10 deg. advance, crank the engine counter-clockwise until the pointer is on 10 deg. advance. Go back to your distributor and you'll see the rotor moved clockwise a bit from the grease mark. Turn the distrubtor housing until the grease mark lines up with the rotor again.

Reinstall the spark plug and distributor cap, but keep the distributor snug enough for starting but you can easily loosen to move it later;

Start the engine; it should start; here, you might want a 2nd person to keep the engine from dying as you time it to whatever you want the advance to be at idle (mine happens to be 18 deg. at 1,000RP for my 347).

Good luck.
