As stated Automotive drawings are very long I have a couple of complete brand X engines, and they are probably 20ft OAL and I just put the machine into auto fold, and it makes a book out of them or you can leave them as a roll. I actually have a few of them scanned as well, just no Mopar ones.
I started my BBM model and the oil pan and timing cover bolt holes are all pretty good, but I do not have the valley, the head deck, and oil & water passeges detailed. When the weather turns bad for winter again I will resume my little project.
So if someone has a model of their Mopar parts I would be willing to trade as I detail mine out further. Obviously its a lot of work. Place up the road will scan a block for about +$350 or so...I should have them do one of my Hemi heads this winter.
