11:5:1 should be pump friendly. mine is 11:5:1 I run pump gas all the time.
Only time I use race gas is when I'm spraying it.
Try it I think you'll be surprised.

Not sure if I want to trust 20K to CA 91.
I can get all gas 92. Thats about as low as I want to go.
1/2 gallon of 114 and 4 1/2 galls of CA 91 and get 93.3 octane. Might end up there.
If I had a dyno close by I would know exactly what kind of fuel was best. But I don't.
I am going to be careful with this engine.
If I get around to doing the IA engine with the parts I still have it would come in at 10.8 CR and would run on 91 all day long. And I could beat on that thing.
