4.7 rebuild & opinion

Got one in my 02 Dakota and love it. Runs fantastic considering I have done very little to improve performance. Can't make it get less than 17 mpg in town. Run's high 14's when it hooks up. No sure grip in it so most of the time it spins bad. Got 65,000 miles on it now and no problems. I keep the oil changed regular as they seem to build up condensation more than normal. That's the only thing bad I've seen with them. Haven't had to do anything to it, knock on wood.
