i only developed a cam angle sensor for my modified turbo3 engines. several tricks i used were embedding a small cylindrical magnet into an indexed tooth of an aftermarket aluminum adjustable cam gear that could be read by a positional hall effect sensor.
that works if you are building an engine management controller but it would be impractical for the engines you are talking about. they have distributors that both read the cam angle to fire the coil and direct the high frequency spark to the correct plug.
I think that would work for my application, the mounting bracket would be a little tricky. Did you drill a hole in the rear timing cover?. I have ms3 that I put together for this project.
