New Build 340/420 Questions

Do what you want but starting small and going up isn't going to hurt anything. Is it real 93 or does the gas station have 87 pumped into their tanks and mix it? Even back in the day my friends wondered why they could run (say) 220 at my station but they had spark knock at the cheaper place down the street using 230 or 240. Ever try testing e85? Believe me I've seen 50% to almost 90%. So you are saying 44-46 degrees total. Not on my motors.
