What octane should I need?

QUOTE=RustyRatRod;1970828488]Regarding Avgas, I have used it in the past. The only Avgas that will be of any benefit to automotive engines, which was 115/145, now is all but gone. You might want to read this.

Nice read triple-R ! Now if I may debate (NOT argue :D ) where I live super (92) is $3.05 , av gas (100LL) is $5.20 , vp is $12. I'm sure you're well aware my theory on well written convincing Internet particles? (Bonjour I'm a supermodel!) here's something I read on the internet (my favorite kind of quote, real life experience) :

you guys can beat yourselfs to death with this debate. mike your a good guy but you sell racefuel and i wouldn't aspect you to say anything other then it's junk just like all the other racefuel sales persons. YOU DO KNOW THE BASE FOR ALL SOCALLED RACEFUEL RIGHT??? NOT ONE COMPANY WILL TELL YOU THE TRUTH BUT I HAD A VERY GOOD BUDDY THAT WORKED FOR TORCO AND YOU WOULD BE SURPRISED... av-gas has been used for 50yrs in racing and is still being used today.... i will sit back and let yeti school you youngster on gas and laugh at some of the dumbshit some of you say..... i run it in a 13 to 1 bbc and spray 200shot with the amsoil mmt octane booster.... i would say over 500 n.o.s passes and went to refreash the engine over the winter and could have used the same bearing rings where fine also....
