The car has an HEI distributor in it and I'm sure the tach is reading too high. At around 60 mph it's reading around 3500 rpm's and that's with 3.55 gears and 245/60/15 tires. At idle it reads around 1100-1200 rpm's and I think it's really closer to 7-800. But things look better with the battery fully charged at this point.
