Its a hugh learning curve at least for me with EFI, I just used the jeep cam position sensor with mine, I forget who made the adaptor to it or I have the one Mad Dart made with a stock distributor, if you want to use that you can. Coil near plug is the way to go with some ls coils, the MS3 drives them no problem, get some aluminum valve covers and drill and tap or if you tig weld some threaded bungs on them and mount.the coils there like mine if you want or off to the side like Chris did on his awesome car.
