Hello!
First off, punctuation is your friend!
Seeing that the speed limit is 70, I don't see that you have any issues. For track purposes, that motor, rear and trans and gear should realy come into it's own around 90-95 and easily run to 120+. Do a search for gear ratios vs speed on the page here or on google, should find what you're looking for but that RPM looks right without consulting a chart.
My 3.73 with 700R4 (.70 overdrive gear in trans) pushes 2600rpm at 70mph.
