What are my options for the pre-he motor? I've read a lot about the crane ignition system (original plan) but have recently stumbled across this pertronix unit:

Has anyone had any experience with the pertronix unit (I've used it in many builds, but the jag v12 info seems lacking)? Pros and cons between the two?
