For timing the engine:

1. Rotate the engine until the notch in the back rim of the crank pulley is aligned with the TDC mark on the timing cover. Since the cam turns at half the rate of the crank, There are two places in the firing order this happens, at tdc for #1 and at tdc for #4 (firing order is 1-3-4-2). To check which one you are at (and to rough check correct timing chain alignment), at tdc on #1 (where you want to be), both #1 valves are closed and the cam lobe points away from the valve. The cam sprocket dowel pin hole (about an inch out from the center of the sprocket) will be just a hair short of straight up 12:00 oclock. The hole for this dowel pin goes thru the distributor gear, the cam sprocket, and into the end of the cam.

2. The engine is now dead on TDC on #1 cylinder. Now you install the distributor in time with the engine. Distributor in hand, locate a drilled dimple on the distributor gear, and rotate the distributor shaft until that dimple aligns with a cast mark on the distributor shaft case. Holding the distributor thus aligned, insert the dizzy into the head with the adjustment slot aligned with and centered on the hold down stud in the head. When the dizzy gear begins to engage with the dizzy drive gear on the cam, let the dizzy shaft begin to turn as the helical gears engage, keeping the dizzy body centered on the adjustment stud as you sock the dizzy home all the way. The dizzy rotor should be pointed at the location of the #1 plug wire tower stud in the cap, or roughly at 10 o'clock, right about the cap clip spot. #3 should be at about 1 o'clock, #4 at about 4 o'clock, and #2 at about 7.

That should get it close enough to run, set the idle speed, and set the idle timing with the light. Hope you get to dance the victory dance soon.
