    Make sure the hot wire going from your ignition to your distributor is not a resistor wire, it it is change it out, you need a full 12 volts for HEI. a points distributor setup will have a resistor on it somewhere to keep from burning up the contacts prematurely.

    It is a very easy swap and well worth it. To avoid any wiring issues, I ran a new piece of wire from the cap to the fuse box.

    My only issue was that the first one I dropped in had a bad module and then I dropped in the dist 180* off the first time. There are a lot of threads on setting your timing/swapping in a new dist. Try these two for starters:

    (the latter was my thread when I did my head rebuild and my dist was off when I put everything back together)
