I am installing my new MSD 6AL set up. Pro Billet Distributor with Blaster 2 coil and aluminum heads. I was wondering what I should gap my plugs at. I have been told 60 thousandths. Any takes?

What's the compression ratio? Any kind of boost being used?

Spark plug gap is dependant on many things. On a mild N/A 9.25:1-10;1 engine, I like to run it .040-.050. Usually closer to .040

scratch my idea, I was thinking for stock. LilJoe, is right, .04 to .050, but if I were you I would say closer to .04
