I am doing some tuning up and getting ready for the Hunting Season that is closing fast. Just doing the regular maintance, changing oil, filters and such. I thought I would install new plugs, and was wondering what is the best plug to be running on airboats. It's a 454, that I have peaking at 5200 RPM's, but rarely run at that.

Any plug (Brand Name) better, last longer, run at the higher RPM's, etc. than the other plugs. cooter

I took the AC Delco's out of my 454 and tossed them a year ago. I've only ran the Champion truck plug since then. They have done me good! I'll have to get the number off of them if you want.
