Haha! Thats awesome! Glad i could persuade you! I LOVE the way my 5.3 runs! I want to put one in the rest of my trucks now! The swap itself is pretty easy and kinda fun. I ended up actually enjoying the wiring aspect... The lame thing is i STILL havent gotten my computer tuned with a 5.3 tune... Its still running a VSS-less 5.7 tune. I Can not wait until i get a good "performance" tune on it and one that reads the VSS as well as park neutral. So, despite that fact that it runs very nice and near perfect all the time, its going to be alot better when its all dialed in.
