    Finally getting close to firing this thing for the first time,was wondering what you guys suggest for spark plugs,temp,gap,etc for boost..Will be on E85,as much as 20lbs of boost,shooting for 1000hp. Running LS3 coils...

    Only one choice really for resisted recessed plugs. BR7EF NGK. Gap them as wide as you can without blowing out spark. A colder resisted conical "drop in plug" isn't made. 20lbs should be fine.

    I would gap them around 15 or 16 and let them ride.
