I have a 1973 maverick with 302 with 4bbl application. Factory plugs are autolite 45 for the 302 with 2bbl. There is a plug selection for 1971 302 with 4bbl and they are autolite #24. Should I use #45 or #24 plug?
should be the 45's. i think the 24's are the 5/8" plug but dont hold me to it. and in a stock engine, you can always run an autolite 46 instead of a 45 (one shade hotter)
