5.9 FI Magnum swap in 73 swinger

That sounds like it might be a good solution! Would you mount the crank sensor above the pulley?

Something like that. I wanted something well contained so I spent a bunch of time trying to figure out a way to mount a wheel to the front of the cam and then use a Gen3 Hemi pickup or something similar mounted to the timing chain cover. It was exotic, complex and getting expensive (and I hadn't even bought anything), so I gave that idea up. So, haven't mocked anything up to see where it would fit, but figured I would keep it high and tight to protect it.

I do have to give credit for the idea to Ehrenburg, though. He suggested it many moons ago when I was asking about the dual pickup that is referenced in the 380 hp SMPI crate motor kit in the MP catalog. BTW, that never existed, so the MP kit is really just for automatics. Even the factory doesn't have a solution for the manual trans in an early car.
