I'm not sure I would do big ends for a cam belt failure. If you think the pistons have hit valves hard enough to bruise the bearings then a shock that large would have me worried about piston fractures, small end and big end bearings. Why only the big ends?
I think a second hand engine does have merit but only if it has a known history and the cost of the engine plus swapping out sways the cost benefit.
If you do swap engines I would want to keep the old one. It is a source of spares and, if nothing else, has scrap value!
If there is a good reason to do big ends only, without being flamed, I would be pleased to know it.
PS: if this is a non Alfa specialist garage I would want to witness the compression test. It seems a coincidence that, "your engine is knackered; oh, lucky you we have a spare one!"
I am a sceptic and I do not believe in coincidence.
