    which ones hold heat more than the other, 45's or 44's ?

    ac delco plugs*

    what should i run in an 84 229 v-6 ?

    i need to pull a coupe plugs and check and see if theyre black or gray or tan or whatm, but im almost positive they will be black, so it would need hotter plug,

    whatever is hotter numbers

    hum,.


    thanks

    higher #s hotter...

    He right--a R43TS plug is colder than a R45TS plug..the 229's used R45TS in most cases just like a small block V8..the hottest plug in that heat range would be a R46TS...you might be able to use extended gap plugs that reach further into the combustion chamber(like R46TSX) but the also might touch the pistons,and the wider gap (.060-080) is more likely to misfire under load,or when oil fouls them..if you need hotter than R46TS plugs,a "nonfouler" with "normal" (R45TS) plugs might work better if they oil foul quickly.. :crazy:

    i wonder if stock 229 pistons are dish or flat

    hmm

    ill most likely put r45tsx in this one then it sounds like

    and run 040 gap though

    and go from there

    im sure the plug sin it now are old and nasty

    it does run pretyt damn good now all other than some cold stumble but i know that the electric choke coil is dead it doesnt shut all the way when cold and it doesnt open ujp alot when warmed up either, jut barely enough to get it off the fast idle cam step

    so im gonna put a new electric choke unit on the carb soon too.


    thanks
