  • Spark Plugs-1964 289 V-8

    I am trying to find out which modern plugs are best for subject engine. It only has about 6000 miles after a complete rebuild.( Also bored .030).I am currently running Champion RH10Cs, which a parts guy recommended in lieu of the H14Y the maint. manual calls for. It appears from the way they look that I need a hotter plug. Any suggestions will be appreciated. Thank you.

      I think the R44S is just a H14Y in a GM AC brand.

      Most of the Forum posters seem to prefer the NGK, Bosch and Nipondenso equivalents.

      You did want BETTER and hotter right? [:0]

      I don't have a Problem with my old stock H14Y's, I would not recommend the fake H14Y's they sell now.

        I've been using Autolite 437 plugs for years on my 259 and 289 engines and Autolite 85 plugs on my R1 engines. No problems, but Stude Rich's response makes me wonder if there's something better????

          I use the 437s on everything, even had them in my '64 R-2 Avanti.

              The "search" function will provide about fifty previous threads with opinions on spark plugs. Let's don't go there another fifty times, please.

                Any Champion plug book for the last 20 years has shown the H14Y replaced by RH18Y. Most stores now will use the stock number 857 instead of the plug number.
