Drag radials

[olds307 and 403]

turbo 400 original 7.5 rear with upgraded moser axles s10posi carrier with 3;23 gears

Later 28 spline? Which posi? I assume not a Gov Bomb. Something like a 275/60R15 would drop highway rpm at 60 mph a good 200 rpm over the 245/60R14. The 225/70R14 is basically 100 rpm less than the 245/60R14 but 100 rpm more than the 275/60R15.
