Hey I just started collecting parts for something similar.
I am working with nissan on stuff and they use a optical trigger wheel in their distributors and cam angle sensors. They usally have 360 holes around the outer edge of wheel and then the number of cylinders for the number of holes around the inner ring. I will be hooking up both the output to interrupt lines on a atmega128 and using mosfets to fire coils in a wasted spark config. I will be able to cover the distributor with a cap machined from plastic or aluminum.
I plan on having two lookup tables(maps) one used for advance and the other for coil dwell. I will use a GM map sensor for load data from the engine.
I am going to try to use some IRF530's but may change to the bosch bip373 if I fry them.
