QUESTION: sorry bout that its a 302

Answer
The distributor cap should be marked with a number 1 between the center coil tower and one of the plug wire towers. If you look at the distributor cap the part that faces the fan consider to 12 o'clock on a clock face.  Number one should be at about 7:00 o'clock. The distributor rotates counter clockwise and the firing order is 1-5-4-2-6-3-7-5. Good luck
