Where is number 1 on the dist. cap?

Good morning fellas,

Attempting to get the engine running again, and like a dummy I did not mark the wires. I have them installed at the plugs. Where on the cap is number 1? BBC 502, MSD Pro Billet Dist. small diameter, not sure if that matters. No reverse 4 and 7.

Firing order should be 1-8-4-3-6-5-7-2.

Thanks,

Jason

#1 in the cap can be wherever you want it to be. Just as long as the rotor is pointing towards that position when the engine is at TDC on the firing stroke. The remaining wires get installed in the cap following the firing order in a clockwise direction.

Typical location for the #1 wire in the cap would be approximately at 5 o'clock when looking from the front of the engine.

See, that is what is eating me up, really do not want to mess anything up. I thought 5 o'clock position, but I am an ex aircraft tech, so I get specific and thing 5, as in right rear of dist.

So, it is 5 when standing in front of the engine, so it would actually be the where the rotor is point, which is toward #1 currently.

Yes. Left click on the drawing I attached to my post above. You should be able to print it out for reference. You might also want to save it to your hard drive for future reference.

I'll add my $.02.

I have an MSD pro billet small diameter distributor with vacuum advance. I installed it in my 5.0 SB Ford in what Ford shows as the "traditional" #1 position. There was virtually no room to advance the timing due to manifold interference - so like a dummy, said to myself - why not run it as the optional setup without the vac advance. I pulled the dist and yanked the advance. Now - a bit older (tho not much smarter) have decided to reinstall the vac advance and move #1 to another position/a couple of gear teeth so I can play with the timing some. I do have a feeling that it's going to cost me some bucks - my plug wires have been very carefully cut to size and nicely mounted in a loom

Hey, thanks for the input. I had to cut off the retainer hooks, and use the bolts provided. Otherwise, the cap was hitting the blowoff valve.

Thanks again, I got it all set, will be firing for the first time shortly, well with the blower.

Man, my stomach is turning.
