Pulley-mounted crank trigger w/stock Magnum EFI - trigger notches?

TT5.9mag said

Sure you could. Your machining would have to be top notch (pun intended) and you could even use the stock crank sensor to generate the signal. The window size will have to be the correct size relative to the diameter of the wheel, which will be different from the oem magnum flexplate but with some math you should be able figure it all out. Good luck.

Got it. There's a company I use to laser cut parts now and then; the results have always been within 0.5mm; probably tighter. This was for a stainless-based tool.

Theoretically, the notch size could be calculated by reducing the size of the original flexplate holes at ratio of the original flexplate diameter vs. the crank pulley diameter, correct?

I'd want to stay away from the OEM sensor for both space, neatness, and reliability. There are a few aftermarket, adjustable crank trigger sensor mounts out there that are affordable enough to make it worthwhile just to avoid headaches, and allow for excellent positioning options.

I don't think I'd want to rely on creating an adapter to work with the fairly flimsy factory mount - which isn't really optimized for use around the crank in the first place. It makes sense to splurge in this one area, IMHO.
