Hey man this is VERY COOL!! One word of caution is that do not advertise too much to the "HEMI" experts that you don't know what you're looking at or doing. That's a sure fire way to get taken advantage of by the devilish "Hemi aficionados" of the universe. I would pull in a long time trusty friend to help you disassemble the engine yourself so that you at least know what is inside the engine before you drop it off. You can' hurt the engine by taking it apart your self as long as you retain that same cadence of "baggin' and taggin'". Take plenty of pics and then drop it off.
