Can I make this work on pump gas?

I ran the numbers too, if your measurements for volume are correct and assuming zero deck with 12cc domes and 68cc chambers, yeah, 11.2:1. I'm in agreement with Rob, if you could relieve the chambers to 75cc or so, then it would still be 10:1 with that and the same .040" gaskets...I'd be sorely tempted to run a .528" solid MP cam, or something similar with that much compression. :)

I honestly have no idea how the fuel blends are in your area, so really only you can answer how it would run on premium pump gas, or E85 for that matter...but I'm inclined to believe it would detonate pretty easy on premium E10 pump...
