Ok guys what plugs are you running in your 427s and is it worth the money for the big buck plugs. I’m running high output coils and Mallory point less Thanks for your input. Tom
Wow! Tom helps me out again! I was just about post this same question. I have a set of RF11YC (#22) in my spare parts that came with boat when I purchased it in July. I assume these are installed in the engines now but not confirmed. I did look around on the Superdisc and these plugs had no mention. My engines had a rather extensive rebuild about 15 years ago with 300 hrs. of use since and they run well. It does have the Pertronic conversion.
Tom...I hope you don't I am hijacking your post, hopefully the 427 experts will reply.
