Looking for any info I can find on off the shelf parts I could use to get this working. This will be running front-driven on a Model B engine. Also attached is a photo of said front drive with a cap on it. Can anyone identify the cap? Thank you!
Somebody's homebuilt electronic - late 50s ear;y 60? I've got a 1929 Mallory centrifugal advance dual point. I bought a Pertronix kit to change it over. You'll need to change the impulse ring. Got anymore detail photos? How does the advance work?
It's functional, but I can't find rebuild parts for this old Mallory anymore, maybe I could convert to electronic?
Sorry to hijack thread btw, but here's another pic. Electronic conversion seems like a nice way to prolong usefulness of obsolete Mallory distributors
Mine is older than that one. It's the first generation and has provisions for the pop out ignition switch. My points are the same. You'll want to make a new point plate to mount the Pertronix on. The magnetic sleeve (in the Pertronix/Mallory kit) is very tight and will need to be opened up a little. I've also considered making some new point blocks and use the contacts and springs from the FD-66 (Ford flathead 8) that is available. 3/8 thick phenolic is available on Fleabay for $9 (4"x4") that will easily make 8-12 points. Here is a pic of the part #s. You need FD-67.
Thanks! I screen capped your post for reference. That confirmed my suspicion that this Mallory shares parentage with the Ford V8 distributors, the vacuum brake is very similar and I've heard it said that Mallory was involved when Ford moved away from the driver's helmet style distributors. It would be really cool to run this as an electronic. Even my later aluminum Y-11 rotors are getting super hard to find.
I make the correct vacuum brake leather pads for Mallory distributors so equipped; the Ford distributors (helmets included) use the exact same piece.
US Patent 1886566 from 1929 - remember a patent covers ideas not specific products. You'll see how the individual parts in the patent were used in different distributors. The brake in mine is a phenolic block.
I feel as I should give this thread an update. I have discovered through some of Dan Iandola's photo archives, photos of this drive installed on this really badass roadster pickup. The story goes, the engine was a B block, C crank and a Cook overhead 4 port head with two winfields. According to the owner of the pickup, it was a prototype one-off ignition. I'm slowing getting it all figured out, but progress is progress!
Retson, pretty sure the cap you show is a GM with the quarter turn clips and you would lift the door to adjust the points with an allen wrench.
