Is the J11Y supposed to be the factory plug on big blocks (specifically, 440's)?
I went looking for some after I just installed a set of the only plugs the parts store had in stock recently (NGK). Needless to say, not impressed with those.
I then snagged up on an original set of Mopar 26422913 P-34P spark plugs still in the box for a pretty good price I think.
Were these the original plugs in our big blocks? Are they rare to find these days?
I paid $20 for the set of 8. How'd I do?
