Thanks Ryan
I use AC Delco 41-602 gap @.035.
I have tried different gaps and have found .035 works best for stock ignition system.
I don't think there is much HP to be had in our LT5's from spark plugs, if anyone has experienced any differance (more power) i would love to hear about it.
I know plugs make a differance on race motors.
