I like having hard numbers. I ran out to the car to check the cranking speed, before i remembered that this is an automatic and doesn't have a tach. Is there an easy way to hook up a tach? i don't have an optical tach, and all the aftermarket tachs i've seen hooked up to the ignition system on a gaser... hmmm. like i said, i don't have a good sense for this starter, i know it started fine when i test drove it, but that was 2000' lower and in a warmer enviornment, and the po probobly warmed it up first. i'll look at the starter a little bit harder. thanks everyone.
