Okay . . FYI . . We've decided on SUNOCO "Maximal Red" . . and according to their chart, it's 116 octane, RON=118 and 114 Motor Octane. with a .708 spec gravity . . kinda light in the density department with their average densities about .745 or so . . But we'll see how it works . .
Price was right for a 55 at Bandimere's . . . and they had it in stock . .
