Default XCV70 on chopped F350 chassis

Howdy there Volvo enthusiasts! First post here, hope I'm mindful of the local etiquette!

I've had a 98 XCV70 sitting in my drive for a couple years now after she spun a rod bearing. Had been chasing blown seals before finally getting parts for the clogged PCV system but had a camshaft seal blow on the highway and get oil starved, got a big squeek and then a tick a tick a tic. Seems like a motor replacement is the simplest option, but wait!

On the other side of the driveway, my 94 F350 351W has been waiting for a PSD 7.3 donor. Found a whole truck rustbucket with no papers yesterday that I hope to bring home shortly. It's rusted out, but the frame and running gear should be fine.

The plan is, the engine and gearbox/trannie go into the 94 Ford, I flog off the 1 ton axles and diffs, trade out for a set of 3/4 ton chevy axles, hack and weld up that frame (looks like I need to lose 28" to fit the XCV70, from 133" to 105"), probably do up some 3/4" or 1" thick steel plate adapters welded to the frame for the body to sit on, maybe line up the subframe bolt pattern. Will either go with the 351W as a powerplant for now or try to clean up my other damaged 7.3 IDI and make it a diesel. Looking to explore using an arduino/rasppi custom dash with a HUD glass and projector for kicks, throw on an artificial horizon and a few other cues.

Yes, this is an insane project. I'm giving myself 2 years to pull it off, given the engine swap takes priority and I'll need to fabricate a gantry for lifting the bodies. Fingers crossed I get to do some of the work in a shop instead of the gravel hah hah hah :D Have access to a 2 ton crane truck but would rather not do work on anything suspended by hydraulics.

Does anyone have any experience on this type of mayhem? Yes I know how to weld and have a red seal buddy to make sure any structural **** is a-ok.

Also I will likely 3d scan every bit of the XCV70 as it comes apart and is moved, if anyone would like 3d printable replicas of various Volvo bits, I'll be scanning with the Einscan 2X pro plus and passing the pointclouds through geomagic for a finished surface mesh usable for additive or subtractive manufacturing.

Hope everyone's staying safe and having fun! I'll put up pictures here slowly as I go.

I've been wrenching for about 18 years... so hopefully I learned something along the way. I'm looking forward to scanning in the Volvo for a parts database anyway, should come in handy for someone. I saw a guy on r/3dprinting just a little while ago printing TPU swaybar bushings for his 240 that looked very functional, and am rather intent on doing CNC gasket cutting as well, very useful for dealing with older vehicles. Got the MPCNC machine half assembled for making things easier there.

I'm sure you all are used to seeing people attempt things like this and fail; I've been putting off this type of project for a decade or more out of better judgement because of exactly the same logic. Every tough thing mechanically that I've tried to do so far has been a miserable series of unpredicted difficulties but I have in the end solved a longer list of problems than I can even remember anymore, with very few instances of admitting defeat... so perhaps I'll have a chance ^_^ Redneck skills go surprisingly far with some googling, tool arsenal and elbow grease.
