I know a guy with a BBC 396 with a Vortex mag and am curious as to what the plug gap should be set at. Right now its at 18 (at the recommendation of a friend). What do you guys say? Fuel is usually around 100 octane and the boat has a 150 shot of nitrous.

18 thou is just right. It also helps to run a plug with a cut back strap. Used to have to cut them back yourself, but Autolite sells them now in thier AR series of plugs. Oh, fyi.........it's VERTEX. Jocko
