Do I set it to .50??

I believe it is .55 or .54 I set mine for .35 because of blower! Are you shooting up? I did'nt look at your mods. I would run bosch platinum +4 if you didnt need to run cold plugs.

I'm running a 306 cam with ported polished heads and orp headers ported MAF CAI and other small things. I set them at .45 for now and I will try them there for a starting point.

You will get a little better performance out of Hotter plug. Normally the 104's or for blower/n2o applications. I would stick with .050" gap bigger spark=more complete burn.

Stock calls for .50. My 327 called for .35 but when it went up in power I gapped to .50. Granted I'm NA but More fuel=hotter spark=more combustion=denser charge....with bigger intake means more fuel needed to burn and the spark hotter means little to me. When I went up someone's lawn tonight out of pure accident it means either lay off the cronic....or the speed.

My bad stock is .50 Where did i get .55-.54 from probably changing to many plugs lately on different cars. Sorry man.
