Hey guys getting close on puttin this thing into my truck was wknderig why spark plugs you guys in the boosted world are using and what kind of gaps you are having? Lets say 8psi or boost on a 292 .40 over with toms pistons and cam 1.94 in valves and 1.6 exh valves lumported if it matters

Sorry this probaby could have been started in electrical!

I'd say, with a HEI, to gap them at .035-.040. Once I had problems with spark blowout. A big spark gap caused it.

I would run .030-.032
