I am running a MSD6AL-2 with the MSD billet dist on a 440 with Edelbrock heads,Diamond Edelbrock dome 13:1 pistons. Drag only no street.Should I use resistor plugs or NON resistor?..... I am currently using Autolite AR3911's. I had this engine broke in on a engine dyno and once we started the pulls it started missing around 5300RPM.Was wondering if the AR3911 are NON-resistor plugs? And if so could they be the cause of the miss? What is the general consensus of the board on what type of plug is used? Thanks !!




Yes they are non resistor and no the fact that they are non resistor is not your problem. What kind of wires are you using?
