I went down to my NAPA dealer for some sparkplugs for my "new" '54 GMC pickup, (the truck has what I believe to be a 55-57 canadian pontiac 261 with a 235 head and 1 bbl rochester carb) and the closest engine they could find in their catalogues was a 265. Can someone recommend a sparkplug for my setup?
thanks alot, mike
