Yeah, I need to hook up a scanner to verify the tach rpm's. But at idle my car tachs at 700-750 rpm's in park so it doesn't seem to be reading high at that point. The LT1 in my 68 Camaro would idle around 575-600 rpm's and is sounded like it had a cam in it because it was so low. I'll take a look at the rear. I just can't believe how rusted it is compared to the rest of the car so it wouldn't surprise me if it's from a different vehicle.
