I did some looking on a GM module that might work for the computor controled timeing , yes they do make one but have to later checkout the wireing details to see if it may work or not , but on the other hand they do still make a Accel HP unit for the ford TFI ign , the wiring I got off a F-250 ford truck with the 460, with the heat sink , planning on installing it on my 2.8 CFI fuel injection conversion , its a pain to get too because the dist is in the back and the TFI module is faceing the firewall , it may never go out because I install a new one but the idea if it does it will be a hot day and out in the middle of nowhere on the side of the road , so having it bolted to a easy place to get too is good , also keep a extra computor with the car also , anyone planning on doing this had better make time to go to the wrecking yards and pick it while you can , most of this stuff is over twenty years old and slowly going away,
