Anyone ever done a points to Pertronix conversion on a M35? I have a 1953 Reo M35 with a Continental OA331 Gasser Motor. The distributor is a Delco-Remy M#
1111556, S# 3 B 11, CW Rotation, Military Ordnance # 7762685. Anyone have any leads or ideas on how to and what part numbers to use for a conversion to a Pertronix Pointless Ignition?

Just curious. I contacted Pertronix and they said that they can't find anything for it. Probably because I told them it was 24 Volts and they didn't look any further.

Thanks,

I have modified both the Reo OA331 and Continental R6602 with the Pertronix. I'll have to double check but I am pretty sure that it was the 1167. I did one with a special ordered 24V module ($125) and another using the standard Pertronix with a 12V regulator epoxied into the large condensor (~$75 + regulator). I replaced the original coil with a 3 ohm pertronix. The R6602 starts better but my real recommendation is to get a civilian distributor. This is what I did with my Reo 400. It also got me a tach drive so that I can use the military tachometer. I got a noticeable improvement even after replacing relatively new and strong points system.

It was the 1167 pertronix. The same as used in early GM inline six distributors. You will have to slightly modify the plate that the points mounted on. I believe that I had to remove the eccentric used to adjust point gap and drill and tap a hole to retain the pertronix.

JasonS, Thank you soo much for your help. So if I got it right, all I need is a 1167 Pertronix unit and nothing else? Once I get the part, I need to modify the mounting/base plate to secure the new unit to my existing distributor. The 1167 works on 24v or do I need to rewire for 12v?

Thanks!

I'd hate to replace the distributor because I just bought this one NOS from either Saturn or Memphis Equipment. Cost me about $180.00 Plus Shipping.

No, the 1167 will not work right out of the box. The pertronix takes the place of the points; using a pass transistor to make the circuit to ground. The pass transistor can tolerate the voltage but the control circuitry cannot. For this reason, you either need to drop the 28V supplied to the red wire of the pertronix using a voltage regulator or you need to purchase a 24V version. It would be easiest for you to purchase the 24V version ($125) if you are uncomfortable putting together an external voltage regulator. I used an LM7812 and mounted it inside the large can condenser/ capacitor.

You also need to use the 3.0 ohm pertronix coil to limit the current through the pertronix module.

I installed the 24V version in my brother's R6602. Everything fits within the stock ignition. I'll take some pictures later this week and post them.

Awesome. I checked Pertronix Website and found the 1167 Iginition Module. This is what I found:

1167 IGNITOR DELCO 6 CYL (12V)
1167N6 IGNITOR DELCO 6 CYL 6V NEG GND
1167P12 IGNITOR DELCO 6 CYL POS GND
1167P6 IGNITOR DELCO 6 CYL 6V NEG GND

Nothing shows for 24V as you mentioned, do you have a part # for that particular model? Also couldn't find the LM7812 on their site. I did find the coils, something like a - 40611 40,000 VOLT FLAME-THROWER (3.0 OHM) BLACK EPOXY - but that's 12V as well. Am I dense? Hate to be a PITA but am seriously wanting to do this.

OK, to simplify things I'll spare the details and just recommend what I think is the easiest way to get the pertonix in your stock disty. When I installed the pertronix in my brother's R6602, he special ordered the pertronix with the 24V option. I'll find out the details, get some pictures, and get back to you. You will also need the pertronix 3.0ohm coil (oil filled, not epoxy). This is all you will need. You will have to modify the mounting plate in the distributor, grind some off of the rotor, and fab up a spacer to go into the high voltage terminal of the coil which mates with the spring in the cap (I used a short screw/ bolt). Give me a few days to get back to you.

Thank you for your help. What was getting me confused was the 24V option on the pertronix unit. When I check the website, they didn't show one available for the 1167 series units. I fully understand the basic 40,000V 3.0 Ohm Coil and having to modify the base of the disty to accomodate the pertronix unit as well as adding the spacer to the HV Output of the coil to the contact on the cap. I've got that all figured out. Just looking for the Part number used for the 24V Option of the pertronix unit.

When I sent an inquiry to Pertronix about 24V they said they didn't have one. It wouldn't be the first time where the sales rep didn't know one was available as 24V systems aren't used in their normal applications. Thank you so much for your patience JasonS. I really do appreciate all of your help! Look forward to your next response.

Cheers!

kind of OT, but i put a pertronix kit in my '72 Chevelle with a 307v8... no modifications were needed on mine, and it was very simple... considering i'm kind of a loser in the electiral department, the directions were simple and made me confident...

ems4ty

Yeah, I've done a pertronix conversion before and it was very simple. I have a 1927 Ford Model-T Hotrod with a Chevy 350 motor. That one has a Pertronix Conversion and was pretty much just drop in place and plug-N-play. Really easy. Just never done it on the deuce with a 24V system before. Pertronix makes really great and effecient products and have never had any problems with them before.

Thanks,
