Magnum Distributor / Cam Sensor only Conversion Cap

[goldduster318]

Hello All,

I created a cap to cover the top of a magnum distributor to make it into only a cam sensor. I had been using the bottom of this distributor for 10 years as the cam sensor for my EFI conversion.

Designed it up in FreeCAD and had @WaterfordMan 3D print it for me.

It has plenty of space under it for the wiring and if the cut of the distributor shaft isn't perfect.

That’s freakin rad. Well done.

@WaterfordMan can print more, you'd have to contact him for pricing if anyone needs one.

with parts this size, you can print them out at 100% on regular letter paper to make sure its right, I had to adjust it a little a couple of times for it to be right.

This is by far the easiest way to put a cam sensor on a small block, obviously it works as intended in a magnum application, I have coil near plug (GM LS coils) so I didn't need the rotor or the regular distributor cap. The blue wire between the outside pins is a pull-up resistor that I needed to add to get the Megasquirt 3 computer to be able to read the hall switch. These things are a dime a dozen so a super low cost item.

Keep the ideas coming @goldduster318 , between us I'll have a whole catalog of parts to support the A-Bodies!

Nice application for 3D printing! Are you going to paint it? 3D printed parts aren't usually water tight, I would suggest painting it to keep out moisture.

@WaterfordMan would have to answer if he thinks its water tight but I washed the engine with no cap on it and ran it for 10 years without an issue so either way I'm not concerned about it.

I certainly wouldn't count on it being "water tight", but in this application it's not a concern. If we needed to consider that for future applications we can do ASA which can be vapor smoothed with acetone. That will create a smooth "candy shell" for the first few layers.
