Best site I’ve seen to
Calculate speed vs rpm for different gear ratios and tire sizes is https://4lo.com/calc/all-calcs.php

Using a calculator eliminates all of the guesswork and opinions. Use the calculator to find the exact rpm you say it’s happy with right here...
And plug in different trans and axle
Ratios and tire sizes to get to that sweet spot at 60, or 65 or whatever speed your hot rodding buddies run at...
