spark plug gap-raised compression

[gravismaximus]

its almost time to put her up for the winter again, i hate NY, wont be long befor theres road salt eating at the winter beater. but the question is when i pull my plugs and regap them what would you gap at. the stroke is the same, .125 domed pistons, .030 over,daviscoil, accel ign mod and accel header plugs, 8mm moroso wires. only have this year on the plugs about 6000 mi. i set them at .050 when i put them in. do you think id get more power at a closer gap, or is the longer arc better for me.

Bigger/smaller gaps won't do much for performance one way or another. If your car is running fine at .050" and not eating up your ignition system, leave it alone.

I agree... leave em. I run mine at .050 too.
