Been running the 318 teen with the comp 268 solid ,have run just under 10k in just over a year,Been using Joe Gibbs 15-40 conventional with Zinc Next change Switching to Syn with Zinc additive (Joe Gibbs).
I would love to see, hear and DRIVE that! I bet it is snappy as heck with that small solid in it. That's a smart choice. Makes me almost wanna vomit when people start getting their little girl panties in a wad when recommending solid. Good for you!
