bnichols04 Member Nov 28, 2005 45 0 7 Jul 11, 2007 #1 Jul 11, 2007 #1 I just bought an 85 302 H.O. mustang engine from my friend and i have it all together but i can't find any sparkplugs that fit it. I bought the autolite 25's but they won't thread in. Does anybody know what plugs this engine gets????
