Distributor for dual plug head.

BRENT in 10-uh-C said:
I have a distributor set-up that I think is pretty cool in that it uses an Early V8 Ford distributor mounted onto a Model-B distributer housing. An E. V8 distributor is basically a dual-ignition 4 cylinder distributor. If I recall correctly, the Nissan Distributor is set up for a leading/trailing timing application, -and if so, some of the performance advantage is lost.

The Nissan twin-fire unit I'm running on my BB RAJO fires the exhaust 4 degrees after the intake fires, I believe. I have my fuel pump wired into the intake side of my switch and when all 8 are firing, when I "clip" the exhaust plugs, you can very much hear the RPM drop !

Yes, this was my point with the comment above. There was no performance advantage when I ran one too. That is why I got rid of mine. Granted, most people would never know that a Nissan twin-fire distributor is an emission distributor and not for performance purposes.

Chris, I would just use a stock distributor with that head since it will make the same horsepower as running the Nissan distributor. Save your money and buy a dual fire distributor that actually has a performance advantage.

I don't know what info you have on the Delco distributor but check out the link. Looks like the 5195 was used on 1918-19 Stutz Series S and G.

Bob, the last I knew, those were $2500.00+ distributors as they are very rare and fit several engines (-even aero applications such as the Hall-Scott). Then, with one of these you must build a drive unit to retrofit it to an A/B Ford engine.

If someone has machining capabilities and wanted to go with a similar looking unit, I would consider using one of Tim Dickson's units. He purchased all of the molds & such from the late Dave Hentschel who manufactured distributors to proxy for Bosch style magnetos. I have used several of these units, -one on a Crane-Simplex and one on a Seagraves Fire Truck. Find a side drive Mag bracket and timing gear cover, -or use an A/B industrial engine governor setup and adapt one of Tim's units.

Those are for single plug heads. Once again my Morton and Brett "Indianapolis" head is dual plug.

Yes correct Brierley’s cyl head is not OHV
Plug placement in an OHV is typically not an option with everything

So what is the head?
If just trying to get it running after 75 years a single plug should be adequate

The head is a Indanapolis. Made by Morton and Brett. As far as I know they made the first OHV for the Model A.
I wish I could show pictures but it is too difficult on this site.

Is this your engine?
