spark plug question
I'm planning on a tune up for the 250 in my truck, and I was wondering if the brand new AC Delco 41-629 plugs I have laying around would work or would it be better if I just go out and buy a different set

Re: spark plug question
What did you figure out on this? I'm in the exact situation.

Re: spark plug question
I,m not familiar with that numbering system. The early 250 engines used a long reach plug with a gasket. The later ones had the standard thread length & a tapered seat.

Re: spark plug question
Yeah I'm just gonna buy new ones. I don't know where those ac delco ones came from but I have 6 brand new ones. The threads are almost twice as long though.
