You would have to get the MSD ignition system that karkraft sells as a kit brand new for 350.00 for ignition. You dont use your computer once you convert it to carb. The MSD box all the work as far as firing and you can use the steeda timing adjuster for timing. I also have COPS for this as well. As for the headers, there a long story. I bought them off of corral from a guy that said they would work on my 99 2 valve and a long story short is they dont fit correct. Im selling them for 100 because they are brand new but i dont know what ford engine it goes to.
