What do you mean by "pin numbera"? Do you need the firing order that the plugs connect in? The connector information?

I WANT TO KNOW WHERE THE PLUG WIRES CONNECT TO THE HEI CAP. DOES IT START WITH NUMBER ONE AND GO AROUND CLOCK WISE IN THE FIRING ORDER OR???

1-8-4-3-6-5-7-2 Chevy distributors rotate one way (clockwise from top IIRC), Pontiacs go the other way. (you said it was a 400 in a LeMans, so I'm assuming it's a Pontiac but you never know...)

Line up the timing marks and the rotor will point to terminal 1 or 6. On chevy's it kinda points to cylinder #1 (front driver) when you've got it lined up with #1 and rear passenger when it's #6. I forget, but assume Poncho wiring is the same but just opposite rotation.

Next time one plug wire at a time. Eventually you'll reach the point like I have where you can rip 'em all off and do it blindfolded...

Ok so where is the number 1 terminal located on the cap, or is it different on every gm dist. I know the firing order and it goes counter clock wise around but the starting point is where i am confused

What part do you line up the timing line on the harmonic and where to on the motor, where they say it supposed to be timied at like mine recomends

9 degrees btdc.

The #1 wire isn't specifically located on the cap. In a situation where all of the wires have been removed and the distributor timing is unknown, simply crank the engine to #1 TDC, remove the cap, note which terminal tower the rotor is pointing at, then make that the spot for your #1 wire. Then run that wire to the #1 plug in the left bank. Continue attaching wires clockwise 8,4,3,6,5,7,2. Now you need to rough time the engine to get it running but you should be close enough to accomplish that with the above technique. Finally, time with a timing light to specs, probably about 8 - 10 degrees BTDC.

The groove in the balancer lines up with the "0" on the timing tab to indicate TDC. The numbers to the side of "0" are degrees BTDC.

I HAVE BEEN TOLD THE FIRING ORDER ON THE DIST CAP IS COUNTER CLOCK WISE ON THE PONTIAC ENGINES. IS THIS TRUE ?SOMEBODY ELSE SAYS FIND NUMBER ONE AND GO CLOCKWISE WHATS UP HELP????

In the email I sent in response to your email I explained how to determine your distributor rotation direction.

I typed "clockwise" in the last response by mistake. I meant to type "counter-clockwise". The distributor rotates counter-clockwise as viewed from the top. A service manual or internet search would have revealed this to you, but then you wouldn't get the chance to thank everyone in lower case letters.
