MagnumMPI swap - crank pickup fix?

if it doesnt have the tone ring it would just be a 360 flywheel but they list it as a "magnum" flywheel curious has any one actually called them to find out?
The Magnum flywheel with out the tone ring is still Magnum specific due to the balance difference. But I believe is machined to LA dimensions so you can slap a crate magnum in a fourspeed car.
I was talking it over with my friend and we wonder if you could machine notches in this one for the EFI tone. Haven't seen one.
