I have a 60 amp Nippondenso off a 4-Runner. It puts out approximately 62 amps at full-field. With the MSD 6A, Two factory puller fans from an Intrepid, a single electric fuel pump, and a CSR reverse flow waterpump the draw is right at 60 amps at 70 degrees F., and I haven't turned the lights on yet.

If you're running a mechanical waterpump and fan then 60 amps should barely fit the bill. You really don't want to run the alternator at full-field, 80% is pushing it for heat considerations. Any more and you should step up.

Mine is mounted on an older DMI low mount with a few modifications.
