If you have an electric engine coolant fan I'd bump it up 10 or 20 amps. Remember, the 60 amps is not at idle. A lot of 60 amp alts only put out 15 to 20 amps at idle. In some cases that's not enough to power the engine fan and the rest. You'll end up with a voltage drop which will cause other problems.

If you've a pulley driven fan then 60 amps is a no brainer..
