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 !!

I have used both the AR3911 and AR3910 in several different BB stroker motors in my car and on the dyno using a MSD 7C in the car and 7AL2 on the dyno, no miss ever One motor is a pump gas 518 that I shift at or above 7000 RPM, the most recent motor I used them in was a used set to break the motor in and it is a 12.8 to compression motor on race gas, it made 872 HP at 6300 RPM and 865 HP at 7000 RPM, no missing with the old plugs Time to figure out what is causing your miss, good luck Let us know what you find BTW, what gap did you set them at?
