I was wondering what I should set the plug gap at? I have a pertronix ignition, edelbrock rpm heads and stock c.r.. The pertronix site does not really say what to set it at, so I was wondering?
I used to gap mine at 35, but the last plug change I did, I went 40 and it seems to run just about the same. I don't think you can do 50, but then again, I've never gapped them that much, so I can't say for sure.
