Yeah I remember that picture. What are you using for your cam signal? Is yours a single coil set up? Batch fire or sequential?
I don't have a steel crank pulley so I will be mounting a ringed wheel like yours to an aluminum pulley. I need to order a 36:1 wheel and take the center out on a lathe to 4.350" or so. I will be welding tabs to the pulley probably 6 and drilling and tapping the wheel to bolt it on somehow.
