The difficulty in removing front sheetmetal depends on how rusty the bolts are. 5/16 bolts aren't too too difficult to break off but all those little nut plates in the grill sides are a pain to braze in again when they come loose. My 1-ton has its top, front radiator support cut to facilitate installing a 2-ton radiator in font of the hoop. I bolted it back in place. To get the radiator out you have to remove it. With that gone it would be easy to slide the engine out through the hoop, though the bellhousing might not clear. Measure it.
Last time I pulled the engine I pulled the complete clip off, which involves breaking all the bolts that hold the front clip to the cab. If you're good with a torch, you can torch them off. I bought a special tip for that purpose -- works really well on bolts to big to break. On the 1-ton there are 2 bolts at the bottom of the hoop that are typically oil soaked that hold the clip to the frame. That's easy. Then there's the wiring and plumbing for accessory fans, A/C condensers etc. I didn't use plugs for such things so I'll have to install those before next time I pull the engine. and, of course I'll have to recharge the A/C.
