Well let me take a stab at this.
Here's what I would do. Make sure the #1 piston is at top dead center.
You may have to remove the plugs and the valve cover. Make sure the #1
valves are closed and #1 piston is at the top of its stroke, mark the
vibration dampener. Now check the distributor, the rotor should be
pointing to the #1 cylinder (about the 2 o'clock position). Install the
plug wires:
#1 goes to the 2 o'clock position on the dizzy,
#2 goes to the 4 o'clock position,
#3 goes to the 10 o'clock position,
#4 goes to the 7 o'clock position.
Now static time it.
It should start.
