so my tuner says i need to run 100 octane so i was wondering if i can run 93 and mix some 108 octane in with it. Plus i really dont want people to know that im running Candy Gas cause then they wont want to race i street race at a spot that is alittle over 1/4 so i built my motor for track you can say.

i havent got a cam yet but ill be going threw AI for that, ill mention to him that id like to run 93 so well see what he says. Now the reason i said mixing the 2 cause it can save me some coin cause that octane is about 6.50-7.00bucks.

If its just a street car and will be running a small cam that keeps the dynamic CR too high then 11.1-11.4:1 like you mention would be a safer bet

Still depends on the combo...personally I think it is a much more common mistake for people to rebuild with too low compression instead of too high. How many 10:1 383 LT1s are there running around built by guys stuck in the SBC train of thought and scared to go higher? I would aim for 12:1-12.5:1 for NA use assuming you are running a cam with a lot of overlap...which you should be if you did your homework before building a high compression NA engine anyway. Any tuner worth their pay can tune a healthy cammed 12.1 LT1 on 93 octane.
