One more thing Spitz.

If you're working with a stock distributor, and a stock advance, the 6 degree lead is a good starting point. Fords always were a little light on this, and frequently 8 or 10 degrees worked better.

Having gone to the trouble to build one of these, I can't imagine you're using a stock distributor without at least a curve kit, or an MSD billet. What you're looking for is total lead, static, plus mechanical. Typically this is around 34 degrees total (with vacuum disconnected), and should be all in by 2200 - 2400 RPM.

Once you know where "0", or TDC is, rev the engine, watch the pointer with a timing light, and see where it stops. Adjust it until it stops at 34. Then let the engine idle. Where the pointer is now will be your initial lead. You may be surprised that this is more like 12 - 14 degrees.

Now hook your vacuum line back up and go cruising.
