I just bought a Deuce with a Morton & Brett OHV conversion head. Mine is a 3 port. I haven't been able to find any information on this head. The ignition is missing from this car. I have found a picture of one. If anyone knows where one of these is laying around please let me know.
That may or may not be "original". Hard to say. Pretty common to see cam driven magnetos on banger race engines. I've got side drives and Bosch mags if you're looking. I've never seen a mag with those type of caps. But that's not saying much.
Here is an old auction for a 3 post head. There are a few pics of the bare casting and an original brochure. https://www.invaluable.com/auction-...ast-iron-ohv-head-ford-a-or-b-84-c-5d5433ca06 Pretty clearly there is no distributor pass thru in this head, and so will require a side or front drive. If you chose to run the dual plugs, ignition options become more limited. The Pierce Arrow double distributor, as seen on the Speedway pic above, is mounted on a standard Bosch mag drive. Isn’t there a fella making a billet timing cover with distributor drive and water pump…? Check with Steve Serr, he would know
Is your head dual plug like the white/yellow one at Speedy Bills? Are you looking for a side drive dual four cylinder setup like that one? Does the head also have a provision to run a vertical, top mounted distributor like a stock 4 cyl.? Apparently not per @Kevin Pharis post above. Although The rocker cover looks like it might have a notch cast in it for one. Any other pics? If so, you can just plug one side of the head’s four plugs, like my Alexander OHV does. You can see the hex plugs adjacent to the exhaust ports. View attachment 6330039
Chris, At one time I had an "Indianapolis" Morton & Brett head like that with the 3 intake ports. These were early Model A heads and Morton & Brett might have modified their Model T patterns to make them. They originally used Model T Fronty rocker arms and the one I had came with an SR Fronty manifold. I kept the Fronty Manifold and rockers and sold the head to Bill Smith. The distributor in the photo is a later Delco made for Stutz. The early ones had quarter turn caps and the later ones used bales to hold the caps on. The head in the photo has Fronty rockers.
