I'd have thought a crank trigger assembly off the balancer ala drag cars and many others - would do nicely for the signal. But who knows?

That's what we did.
We were using a FAST XIM box with a SBC crank trigger on the front of the crank reporting timing to to the EZ EFI 2.0 system. Thing is, the EZ EFI takes limited functions. EFI sportsman is "Supposed to work" but when push came to shove, they said it's better to run a distributor, which this motor will get, but then I didn't want that in this Camaro. The LS looks more like a Ford motor at this point...
Funny thing, the Mamo motor is getting EFI Sportsman anyway, but now has a standard LS crank and cam sensor, so it will all run natively without concern for square or sine wave inputs. We went simpler.
Next ones will be ALL GM, no aftermarket EFI.
