[hoppy]

Something is not computing, and maybe its my speedo gear.
At indicated 80 mph I am turning +/- 4000/4100
Rear tires are Yoko 295/50/15, I think about 26.5 Dia.

I have been told that with 3.31's I should be turning about 31-3200 rpm @ 75-80 mph

I don't want to give up the top loader, just slow the engine down a bit at cruise speed
