2008 is not the best for conversion. Not saying it's bad, it's just the 08 has displacement on demand and it uses an ECM and a TCM unlike the older engines (07 classic and older) with just a PCM controlling the engine and transmission. If you're going to use the 08, I would change out the lifters and disable the displacement on demand and run an aftermarket computer.
FWIW, 2002 is the best donor IMHO because it's the last year for drive by cable. 2003-up uses drive by wire which works fine, but gives you a horrible pedal feel which can't be changed using the factory computer.
