Cool. This is turning into some good information. I had searched a week or so back to see if another manufacturer had something similar but I failed even after looking specifically at the Mallory site

. With your confirmation I was able to locate it. Another cool option. At least it appears that way. I'll have to see if I can dig up the specs for the sensors somehow.

Freaky timing since I just spoke to their tech Monday about this and it wasn't mentioned but... I also received a marketing email from the folks at ATI today introducing some new damper shells they are producing with a 24x reluctor wheel built into the shell. Not enough details yet to know if they would be of use to a SBC/BBC conversion or not. Just that they come in 6" and 7" sizes. Not sure if I could take my existing ATI Superdamper and put the guts in a new shell or not. They are "made for AEM Infinity Systems".
Here's the press release.
