I am considering trying spark plug indexing . I have read several online articles and not sure it's worth the hassle. What's your opinion?
I have a 13.4 : 1 SBC ,355 CID, Dart 230 cast iron heads, Hilborn stack injection, alky, MSD 12LT mag. I have no interference problems with spark plug to piston. Running NGK 8,gapped at .018.
Thanks . George
