Re: Plug Gap on 352 v8 to compensate for unleaded fuel????

There are a couple of other things to consider when selecting spark plugs for these OHV V-8 engines. Should one go with the standard exposure center electrode or a projected electrode (e.g., Y series Champions or S series ACs) spark plug? Also, resistor or non-resistor type? And what about the new platinum plugs with one, two, and more grounds? I would say go with a resistor projected electrode plug along with solid wire, non-resistor, high tension wires. The extra cost for the platinum spark plugs is probably not warranted due to the small amount of miles these cars are usually driven. The projected electrode type plugs will not work on the l-head straight 8s. Just some thoughts ...
