Re: [GFS] Spark plugs

[<mmyhrvold@xxxxxxxxxxxxxxx>]

I use the same plugs that I use in my 383 road runner, Champion J11Y if I can find them, If not, J12YC.
The best answer is to use what works.  The gasoline today is not at all the same as the gas in the 1950's.  The gas today is made for pressurized fuel injection systems, not for carburetors. Also if you use electronic ignition instead of the point distributor, you get a hotter spark and may not need as hot a plug.  My GC 350 Fury has points, Packard 440 solid core wires (left over form the 1960's) and runs fine.
