Well I have run into our first snag. The 08 5.3L engine looks like it is bad as it has a very tight spot in the rotation (with the plugs out) and it is not freeing up. The replacement setup is (hopefully) on the way and it is an 08 LY6 engine and 6l90 trans. It looks like it may be a score because the new one is a 6.0L and it should have the new HD 6 speed automatic, however; it may require some re-work due to the trans being different and possibly the motor mounts as the new engine came from an 08 Silverado HD. I also have to figure out who can do the programming for the new combo as the trans control module is located inside of the transmission pan and all the research I did was for the 5.3 combo. I'll let you know how it all turns out.
