EDIS with 7427 possible?

[1project2many]

What year engine? The 95 uses a crank sensor on the front of the engine. Not sure about 92-94.

3800 ignition system is similar to 3.8 2nd gen. There is quite a bit here including waveforms (p. 4 or 5):

Some good stuff on the older 3.8 (ICM synched spark) on P. 5 & 6

Much rather use the 7x dis system. Six shooter do you have the info on tdc position of sensor and what degrees everything is.

This page, even though it's for Megasquirt has some pretty good info on the trigger side of things. http://www.megamanual.com/ms2/GM_DIS.htm
