I have a 51 chevy truck with a 1958 235 in it. What is the correct plug to put in it. It had a bosh plug in it and I purchased a Delco that was recommeded from one of the part houses. The issue is the Delco is a little taller and I'm some what afraid to use it. I don't know if the bosh was the right one to begin with. help Thanks
AC $ 45 ~ NOT R45 ! . Also look it up on the NGK site and use thier copper core plug . DO NOT use platinum sparkplugs in these old tech engines ! . If you look in recent messages , this has been covered in detail including P/N's...
