They have an annual "all Ford" powered show in Honolulu, BUT, subject to room available they will let a few non Ford powered hot rods sneak in. Parked WAY in the back though.
They also have "Camaro" only shows, so it's all good.
Yeah mine is .82 with 3.31 and I'm running 2500 at 70 mph (corrected with GPS). As MY motor does NOT like dropping below 2000 rpm I had little choice but to go with a .82. It sure is nice, even though the rpm drop is not nearly as significant as a .6 would be. Works well for my setup.
