I keep an eye open for projects down the road, do you have a diagram and/or a parts list for a complete setup?
Why BMW crank trigger- easy bolt-on?
How does the BMW crank trigger work with the original question? (360) or was that an oversight? If so, is there a specific 8 cyl trigger that would work?
This is the sort of thing that would require a bit of fabrication (or a similar aftermarket crank trigger with a 60-2 or 36-1 pattern) and some sort of aftermarket control unit - MicroSquirt if you're on a budget, maybe something like a Haltec VEC if you have a larger budget, want more I/O, and don't care if the unit may be used to control EFI down the road. Accuracy and tuning are often a lot more important than spark energy - although LS1 coils are no slouch there; I'd put them as in the same league as an MSD-6A or most other aftermarket boxes.
