The firing order is 1-8-4-3-6-5-7-2.
The distributor rotates in a clockwise direction. The engine must be on the compression stroke on the #1 cylinder. Line up the timing marks. Remove the cap and the rotor should be pointing to approximately the 5 o'clock position.

Good Luck

Order is 18436572. Put the timing mark on the crank at 0 and the rotor should be pointing either to the firewall or the front of the engine. If at the wall, turn the crank one more time and it is now pointing at the #1 wire position on the distributor.
