I now have over 1000 miles on the swap! I am driving it to work everyday now. I put the tranny from my other truck in there and it works great. Haven't got a good check on fuel mileage yet-everytime I come to a stop I just HAVE to roast the tires! It will eat them pretty good from a 30mph punch so I have been doing that a lot too! The next mod will be some new back tires. The only things I still have to do before I am calling it completely finished are: put the glovebox back in, get the cruise working, and tune out some part throttle detonation I am getting. I am extremely pleased with the swap-well worth the effort. Those guys that invented the small block back in 1955 should have invented the ls1 instead!
