Could you run a tighter ring gap using e85 compared to other pump gas? This is for a n/a stock bottom ly6..mainly street use/abuse.

Could you? Yes. Should you? NO.

A lot of these motors started life at GM were/are flex fuel rated...nothing special for the ring gaps that I'm aware of.

I didn't think so since I couldn't find anything on the interweb saying otherwise. I was just curious since e85 burns cooler that maybe you wouldn't need a standard gap size. The reason I ask is because I found out the top ring is gapped to .015 which seems too tight..
