Here's one that might ring a bell Rich...

Leominster Motor Sales Ford, Leominster MA, 1963

Joe, Leominster was a few towns west on RT 2 from my hometown of Acton. Didn't go that way too often, always more to do heading east into Boston and 'burbs. Wachusett Mountain is near Leomenter, a whopping 2005 ft!!!! Hardly considered a hill in Colorado where I lived on the slopes of Pikes Peak...14,000+ ft!

Why so many spark plug wires?? Am I seeing that correctly?

Dual plug cylinder heads, running only one spark plug to the side creates slightly uneven and slower ignition, as it has to travel across the cylinder, but using two spark plugs — one on each side — results in more even flame propagation

Ford used dual spark plugs on some of their engines, I assume for emissions reasons. I have sen older Ford Rangers with 4 cylinders that had 8 spark plugs.

Thanks...had never heard of that.

Yup, my sister had one many years ago, 2300CC.

I feel this may be especially true on a blown Flathead, to assure correct timing. the quench area around the valves and adjacent ridge to the bore may be especially prone to predetonation or detonation at unspecified, random timing. Timed spark is better and safer than that.
If it runs on fuel at all. What a death trap !
