I hear you there, I still use the factory 10 bolt w/ 2.73’s – Shortened 31 spline 8.8 is in the works.
I have ran it exclusively since 2006 in my Z28. I switch to 93 at the end of the season to store it, but thats it. I have 2 e85 stations within 5 miles of me so I’m good there, road trips kind of suck BUT I can run 93 if I need to (HP Tuners FTW). Even being N/A, its a different machine on e85.
