Re: 84 force 125 firing order
First, if you have a distributor, it is NOT an 84 block. It is earlier since by 84 they had Prestolite distributorless ignition.
NOW: firing order is 1324 with top cylinder being #1. The plug wire closest to the block and facing backward is #1 (about 4-5 O'clock position looking up at the distributor cap) You go around clockwise looking up at the distributor cap.
