I had Christo and Joe install a 4.7, ecu and transmission, mated to the transfer case off of my high mileage '97 80 series driveline during the summer of 2011. Christo had the truck for about 3 weeks total, because I told him to take his time. I have been extremely pleased with the results, factory air, cruise, and all gauges, etc, work properly, and stainless steel custom exhaust sounds awesome. Shifter and trans case lever are in stock position, and unless you are a mud member, you would never know that the truck did not come from the factory with the 2UZ. Motor runs cool and the truck is much faster and more powerful than stock, I don't slow down at all going up hill. I have 33's on it right now, but I have had Slee install 4.88's and I will put on 315's in the next three months. I apologize for the lack of photos, I have left the truck in Henderson NV as my "out-west" vehicle, so I don't have photos, but I will bring it back to northern VA in early December, and can get some photos then. Getting about 16.5 mpg on the freeway, about 15.8 mpg surface road/highway mix, per scangauge adjusted for tire circumference.
