A couple of things, the A-series be it A12 pr A15 will run 6000 RPMs for hours one end. Back when our coupe was a road car we did a road trip where the car was floored for 2 hours, then some stop and go for 45 minutes then floored for 2 hours, stopped for gas, then floored for another hour....................this continued for pretty much three days. Amazining we didn't get a ticket since we seldom went below 80 MPH. The engine had no issue whatsoever, your hearing may suffer but not the motor.

While smaller circumference tires will up the RPM's it may end up increasing the speed ever so slightly (think 2 mph) as these cars do hit the aero wall starting about 75 mph and the stock gearboxes have pretty big RPM gaps in them.

Get a moderate cam, port the head, install a Weber 32/36 carb, decent shocks some sway bars and 185/60 tires and have fun with it.
