What would be the best plug to run in a 340 with 11.5:1 and solid lift w/mallory hyfire VI-AL ignition?

Just getting ready to fire it up and want to make sure I get the best plug. Also isn't the gap supposed to be .040-.045 with the hot ignition modules?



Yes! Always run a larger gap with the ignition box systems. I do on my drag car and it works great. Hard to reccomend a specific plug though because ask 5 different people and get 5 different answers...
