I have 54 235 in my 49. It still has the old turning body vac advance dizzy. I’m looking for a recomendation for a basic mechanical advance non HEI style dizzy. In the end it will just be an oil pump drive that distributes spark and locates the pertronics.

Word of advice from someone who has been there. STAY AWAY FROM PERTRONICS ignition systems. If you want original looking electronic distributor buy Langdons. JMO

If you don't want the housing to move, just don't connect the vacuum line, or plug the line with a lead BB. Then all you'll have is the mechanical advance, which won't be enough for good gas mileage. The people who designed the original advance system weren't backwoods rubes who just fell off a turnip truck.
There are two types of Pertronix systems- - - -the ones that have failed, and the ones that are going to. I'm 75, and a little crippled up from a motorcycle wreck, but I think I could outrun anybody who tries to GIVE me a Pertronix ignition! I'm in the process of modifying a stovebolt distributor to use an OEM general Motors reluctor and pickup coil, which will trigger a remotely-mounted GM module on a heat sink. Untold millions of those systems have worked well for nearly 50 years, with a very low failure rate. They're also "idiot proof"- - - - -no current flows anywhere, even if the ignition switch is left on accidentally, until the module senses a signal from the reluctor indicating the distributor is turning.

My Langdon’s distributor has also been very good. X2 on this one.

If all you are looking to do is eliminate the vacuum advance, and don’t want the vacuum canister, cut off the canister, spot weld the two pieces of the octane selector plate and the advance slider together, then dress it down all nice and smooth. Now you have just a clamp arrangement (bolt the selector to the block and clamp distributor, you can still adjust the distributor for some initial timing) and the mechanical advance will provide something usually in the 12-14 distributor degree advance (24-28 degrees at the motor at full advance). Not a great set up for a lot of street driving but workable for a race motor.
On the other hand, if you are looking to have the Petronix act as a trigger for say a computer controlled spark, that is one way to use the 235 distributor with just mechanical advance. If that is the direction you are going, I would love to hear how you are going about it. Be nice to see something new in 235 ignitions.

All I need is a sensor platform for the ecu, an oil pump drive and a distribution point for the spark. I’d go to a Ford EDIS coil pack but thats not “in keeping” with the look.
