but it is looking real damn good even in skinny jeans...
about the diesel swap, like any major powertrain swap....make sure you have it operational outside of the vehicle radiator/fan assembly to transfer case.....get it working stand alone.
from there you can estimate your plumbing and wiring scenarios to a fair degree. once the majority of that is gathered up and collecting dust do the measuring for the real estate estimates from what is under the hood to whats needed by the new system.
then the cross member situations can be mulled over....and i would make the core and inners removable long before the swap is attempted as well.
that is how i am able to do the physical swap processes quickly.... otherwise the hours stack up quick and your not able to drive it.
one guy i did some work for years ago was bragging at the parts store it only took 12 hours to do his swap....(rather for me to install his swap) he forgot about the three different days of tearing apart and reassembling his truck at various points prior over the summer for various preparations and the 20 hours i had into the harness, and 10-15 hours of various adjustments afterwards etc etc etc....
i have been looking at some of the 4bt offerings on the e baaaaae and my old 7.3 lately because i have had some issues with my newer 6.2 engines and really am ready for more power again. prep work alone for the old worn out 7.3 including cups and gaskets is over 200 hours being optimistic... in work life thats 10 weekends....or 6 months. with a family that can turn into a year easy....if my engine was ready to go and in prime shape i would feel differently for sure...
but it is not...soooo, faaaawwwk that.
4bt on the other hand i can get in good running condition with transmissions coolng systems and fead etc.......i think i would have 20 hours prep and a 1 day install. hopefully the 6.2 i am assembling right now holds me over. but for a main wheeler i am not so sure i would want a diesel....i drive the road mostly and its the only reason i run a diesel. if your a diesel guy and comfortable working on them then its a non issue i guess...just some random thoughts on the matter...just want to see your kid on the trail with ya as often as possible....enjoy this time with them as its short....
