I've got 8K on yhe one I bought from them....very good people to deal with...motor is strong, smooth everything as advertised...I'd buy from them again in a heartbeat...my truck is 90% DD and I tow a bass boat most every weekend....good mileage, etc....I don't need a super rumpity ring-a-ding race motor that I have to mess with constantly or one that drives me nuts just trying to make it run right....I have the confidence to drive this one cross country any time....so far mostly to Arkansas, but I drove to Bristol and Darlington with nary a hiccup....Mobil 1 from day one....
