Alright,

When your engine is at TDC, the rotor will be pointing to the number 1 cylinder. If it's not, you will have to rotate the distributor until the tip of the rotor is pointing to the number 1 cylinder, then go in firing order, clockwise? (it's clockwise in my mustang) around the distributor and put your plugs in.

Doc here,

The STOCK location will be between 5 and 7 O'clock on the Cap..

Now you see why we say If possible, leave it in the Stock position? It's nothing but trouble for the next guy to figure out.

Pull number 1 Plug, Pull the left Valve cover, Rotate the engine until you have #1 TDC, Compression, Both Intake And Exhaust Valves DEAD closed (no lifter pressure) Check your timing marks.

If the marks aren't aligned, you have mechanical problems, (jumped Timing chain, or slipped pulley) If they do line up:

Pull the distributer cap, the rotor should be pointed to the number 1 plug tower. (dead on) To be sure, make a mark on the dizzy base with a marker in the center of the #1 tower location, use a straight edge, and line the rotor to the mark. This should be between 5 and 7 O'clock location on the Dizzy.

If the rotor is Off, but the timing marks line up OK, Withdraw the dizzy, and set the rotor for #1 Plug tower in the 7 'O clock position.

NOTE : as you pull the distributer, it will turn as much as a tower width, this is because the gears are diagonal cut.

When you go to install the dizzy for #1, note the amount of travel it makes as it seats into the block, and set it BACK an equal amount of distance, so that when it is bottomed out, It is DEAD on #1 tower.

Going Clockwise, the fire order is : 1 8 4 3 6 5 7 2, make sure all your wires conform to the number 1 location.



Cylinder locations:
8--------------7
6--------------5
4--------------3
2--------------1

Front of the car

Pass side | Drivers side


That should get you running again.

Doc

What type of dist. do ypu have, HEI or small dia. unit?

Don't stick #1 wherever. All repair books use the factory location and the next person that works on it will go to the standard location and be wrong.

Doc here,

It sounds as if you have made so many changes to it now (without success) To just plunk it down, and wire it accordingly you are at your own mercy's..you need to wire it as my above post shows.

YES .. you can wire #1 plug ANYWHERE you want..and you can work on it forever if you ever blow a timing chain..cuz you will probably reset the dizzy to standard..with a new gear set..and now the fire order is off..

Be advised during all this "expermentation.." healthy backfires are murder on older timing chains (tends to split them in two) and Cams..(force of a rotating mass being dead stopped and thrust backward in a millisecond..

Unless there are clearance issues, there is no advantage to moving the fire order from stock location..and invites future grief when things go wrong..

Just my thoughts..

Doc
