Doing those things is no problem as long as the computer controls the advance correctly. The way it is modded you can take it apart as easily as if you had points in it.
I would like to see someone take the time to create a step-by-step how-to on this EFI thing. The reason is because once you get the ignition system ironed out correctly, it is VERY obvious that the weak link is a carb that spits gas into a single manifold that feeds 6 separate firing systems in an exacting sequence. On the other hand, it IS a stovebolt and maybe the expense or trouble is a bridge too far?
