I have 3 7060s and can sell the nearly new '27 and related gear lol (Actually its a 6395, essentially the same thing, as you know)

After doing more research I think I'm just going to MPI mod the 7427 for the time being, see how it runs, then leave OBD1 behind and go to something newer and faster that can handle an ethanol sensor. The fact that I can walk into ANY parts house and immediately get a new PCM for 100 bucks is a huge positive to keeping what I have, however, so if it idles cleanly with the bigger injectors on it then I may just keep it.
