If you have an aftermarket distributor, the timing mark on it is incorrect. Every dizzy I have bought has had the timing mark improperly marked, by one plug (I've bought Napa, AutoZone, CarQuest, Advanced auto Parts, etc, not OEM yet) Unplug all of the plugs and move the mark on the cap one in the counterclockwise direction.

im doing some more reading on timing chain and it says to count links after install i would think that if timing chain is installed without head on like i did it it would be perfect.. i do know what your talking about on the wires either way i move them it doesnt help ive also tried that but no luck

i got it running i went and bought a book and just followed the instructions and it was good except for the dist. the one in the jeep is a motorcraft one (dont know why) and i finally just 180 the dist because it was popping through intake so i been around long enough that the timing is not right but i knew 100% the timing chain was right and it fired right up with doing this
ok for those doing a search i hate to tell you but just go buy a book even with a step by step guide with pictures its much easier with a book, and if this is your 1st time doing a timing chain its probably not the one to learn on, just being honest
