Always test.

Good morning to all,
As Dave advised always test, every combination requires something different.
VP C-12 will work well , I've found on our lower compression engines that the C-11 was slightly better, but again everyone's combination is different ( even within similar engine family's) Timing , Camshaft , Jetting and other outside factors will have a bearing on the "ultimate" fuel for your engine combination. Good luck and enjoy your accomplishments found during your testing.
