Reply to "Spark Plugs Question 351 C"

Thanks a lot for the answers. Mark, I once in a while realized that one plug refused to work, so motor working on 7 cylinders was shaking a little bit. I replaced that one plug and everything was right. So, I just thought maybe the ACDelco plugs are not supposed to work in a 351 C. So, following your advices, I ordered the Autolite 25. Bosch, by the way, sold me the crossreferenced HR10BC (ACDelco R45 TS). Those plugs are much smaller in length, so I will return them today. They definetely will not fit onto the cable shaft-contact of the wires. Anyway thanks a lot for support and for the "plug list" George. Walt
