Can someone enlighten me as to this?
I can second the advice above about short engines etc
“Short” means without cylinder heads, usually sold to racing car builders as they’ll work on the head or fit aftermarket ones anyway. But for an overheated engine the head is likely warped anyway, it’s the first thing to go usually, the rest of the engine is usually fine unless you got it hot enough to seize it (unlikely, it would be running like a skeleton having a **** in a biscuit tin).
If the original post meant ‘small’ block, then that different, that’s the smaller (relatively, Ford still made a 5.8l version) of the Ford v8 family (big block was the truck version). Then that won’t fit as it was never AFAIK made in a transverse configuration. I presumed it was a joke anyway?
Other than that I’d second getting onto Ford about it as it’s relatively new, and if no joy there have a look round the online recyclers as someone will be scrapping a car with that engine.
