Need a little help here. Getting ready to fire up my 354H and was wondering what spark plug to use. I currently have Autolite 85's set at .035 but would like confirmation.
My engine is normally aspirated with a 650 AVS, MSD electronic ignition, 10.5:1 CR and 270 adv dur cam. I will be running pump gas at 93 octane.
Regards,
Mike
