100 amps but what is the ramp up to that 100amps? You need to find out what it puts out at idle and cruise before you can determine if it's right. If it never puts out those 100amps until 3500rpm then it won't do you much good.

My $45 cs130 for a Ford Tractor and my part store starter for a 318 worked better than any of the Powermaster alternators or starters I wasted my money on for my 451/472. Hot lapping and never missed a beat.
