spark plugs?

The dui instructions should give a spark plug gap - will be much wider than stock one. Don't think manufacturer of plugs is going to matter too much,that dizzy will fire em off. As far as heat range, you probably want to start with a fresh set of what you were running before and get a read. If all you changed was the distributor they should be fine. Make sure you run a 10 gage wire to the distributor. Good time to install a relay under the dash. 12 v from the ignition switch (wire that now goes to the distributor/coil) to the relay coil, other side of relay coil to a good ground. 12v from the battery to common contact of relay, no contact of relay to the distributor. Might consider adding a hiddent switch in line with the wire from the ignition switch to the relay coil, nice little theft deterent. Have a dui in my 258, it's a beast. Only problem I had was blasting the crap out of myself trying to static time it.
