can we talk plug gaps?

I run .045 just to be safe.
Running a GM HEI conversion that can go larger but think about this.
If you gap it larger till you get a miss then that spark is very likely to go somewhere you dont want it going.
It can burn right through a plug wire, or rotor ruining them.
It can even burn/short the coil internally.

.045 - .050 would be the max I'd go for safety.


OH, also some plugs are really close to the pistons already and opening the gap too much can cause it to touch the piston.

Just my own experience and oppinion.
