I have a '48 F-1 with its original "H" series flathead six. Distributor on side of engine, not in front like the "G" series. All Ford literature I have (including shop manual) says the points should be adjusted to between 0.024" and 0.026". That's swell, but no one lists a dwell angle. Maybe Henry didn't care!! My Allen distributor machine wants to measure it, so does anyone know what it should be? Or doesn't it matter? Thanks! Norm

i am sure someone has a spec book ,but on a single set of points , divide 360 degrees by 6, then figure 7,1/2 degees on each side of the ramp. so its 60 minus 15 for a dwell of 45 for a 6 cylinder 30 for an 8

The dwell for the 6 should be about 36-42 degrees. Here is a link to a tune up specs chart. http://www.tpocr.com/ford.html and a pdf file of another http://www.flatheadv8.org/35-51distspecs.pdf Tom

Norm: Here is probably more than you wanted to know about tuning your Ford.

Here is even more: It will give you point gap, dwell angle, etc. When we set up distributors on our Sun machine, we usually set the dwell a degree or two less than the chart. It seems to give a bit better performance on today's fuels.

This looks like it's from a Motor Manual! Is that right? Thanks! Norm

It could be, but I'm not sure. It was included in a box full of such information that I rescued when the local Ford garage, where I once worked, was being torn down. I keep it with my Sun machine equipment for ready reference. I have other such data, but I like this one because it is on just two pages. Today, our shop uses an online shop manual service covering everything on wheels. It is expensive, but absolutely essential as vehicles have gotten ungodly complicated. Ford was not noted for lots of reference material, and didn't even publish a comprehensive shop manual for many years, preferring "bulletins" instead. That approach wasn't uncommon. For many years "Ma Bell" didn't even allow their linemen to carry a volt-ohmmeter!
