Hello,
I have a '51 M37 (Canadian version) with the 251 cu in engine. It has been converted from the shielded ignition system to a standard distributor, wires and plugs. I'd like to give 'er a new set of plugs, but was wondering if anyone could tell me what plugs to use? The plugs that were in it when I bought it are NGK BR6S ... does that sound right?

Thanks and Merry Christmas,
Dan

I would imagine the same plugs as any similar civ truck w a 251, and there prob the same as the 230 anyway.
