Did a search and found some conflicting results. I want to know about increasing the spark plug gap, specific to my truck. I have an intermittant miss in the truck so it's time for a tune up, including changing the plugs. I'm currently running AC R45TS (I believe). I know that the recommended gap is .045, but I've heard recommendations both for and against increasing the spark plug gap. The heat range seems fine, so I'll stick with the same plug. The engine is a mild 350, flat tops and 882 heads. The ignition consists of a Crane Cams optical ignition points replacement, an MSD Blaster 2 coil, MSD cap and rotor and Taylor spiral-pro wires. Should I run .045" or increase the gap, and if so, how much?
