The 59 GMC 370 with 270 6cyl. engine. I want to put a new set of plugs in it. Never had any since I got it and I think I may have fouled one of the old ones by flooding it. I have not removed any, it may have an assortment of plugs in it.
My manual says AC 44 commercial. I have not went to my FLAPS yet, because I want to know what I am asking for first.
Will there be a 44 (commercial) or just a plain 44? Or is there a replacement plug in another brand that would do just as well? Thanks.
