Hey Darius, thanks for the link, do you update this link often?  I am looking at possible the 440 TnT from my 300 in the GTX -- or, go retromod with a 5.7 HEMI w/ tranny as I have sourced them complete with computer(s) for $3000 bucks!  But, I am not at the "What engine do I want to install in this GTX" stage yet.  Looks like I am doing all the parts you have not replaced yet on yours!  My initial goal is to get it strengthened, all sheet metal installed, and lined up, correctly fit.  I am leaning towards the 440 option as this would keep it more 'original', however I just don't know...yet.  
The Satellite I want to have a daily driver, so, I don't know if the 318 will be the way to go as it's messy; smokey, and all...but, we shall see! 
C-141, been on them long distance; Germany to Uganda non stop, not very comfortable, but, after watching the loadmasters rack out on the seats, I figured out how to do it as there was not many soldiers on this flight!  The crapper on a 141 is pathetic!
