Below are 2 of my plugs on a carb'd 383 stroker. These are accel 276s shorty plugs for headers. According to accel, they are HOT plugs (they claim that the last digit is the temp ranging from 1 to 8?? and these are 6). These are NON resistor with an msd6 and coil
The pics should show that the white center part is black but thiny covered and the electrode part looks lighter. Any oil that you see is from the valve cover oil that sometimes runs down when I dont seal it good
So my question is, do you think Im running ok or am I too lean / too rich / or is the plug wrong? I was thinking of going with a cooler plug with a resistor???
