there are some very clever/skilled people out there!

Yes, massive respect to the engineering behind those projects.

My toolmaker apprentice master had a Jaguar engine and running gear in his MK2 Cortina. He’d cut and re-rolled the arches so that the wheels fitted, and chopped various other parts as well to make it all fit.
My mate fitted a 4.7 litre Nissan diesel engine in to his brand new Land Rover 90. Plenty of mods required on that as the exhaust manifold is on the opposite side to a Land Rover, and the original drive shafts were too long. It got some shocked expressions from people as we overtook them whilst towing the hot rod.
On a lesser scale, I fitted an Escort RS2000 engine in to my MK3 Cortina, but apart from fabricating a new exhaust to meet up with the tubular 4-2-1 manifold, it was relatively straightforward. The exhaust was gratis, courtesy of my MOD employers stainless steel from stores. If questioned, my apprentice master said it was ‘training’ on a mandrel bender, sheet metal bender training for the silencers and Tig welding training for welding it all up. Just reminded me how much I miss that place and their tools and machinery. Oh, and their stores.
