race gas or pump non ethanol premium, which to use

It’s an experience for sure. The time I spend with my brother working on the vintage F1 / F2 / Atlantic cars and seeing him built the Cosworth DFV’s / DBG’s, etc. then running them on the dyno is impressive to say the least. Nothing like an 11k screaming 3 liter. It’s the same chilling and talking with The banned forever YR. His knowledge of push rod motors is awesome. We’re going to run my motor soon then make the changes run it again, then play with some fuel / tuning to see how the different fuels compare.
