Keep an eye on the oil pressure gauge and engine temps. If the oil pressure drops (or increases for that matter!) stop the engine asap. If the temps get too hot, stop the engine. Check the oil level in case water is getting in the sump. Keep your fingers crossed.

The worst is probably that the plain bearings `(big end/mains etc "picked up" when it was seizing, welding them to the shaft and them spinning them, which could knacker them badly

Just rebuilt a Pinto for a friend that had been started similar to yours, Its ended up with new mains and big end bearings and a cam due to scoring
Luckily the crank was salvageable

Hopefully you've had better luck

If it were me I'b be tempted to check a main bearing and a big end bearing as a rough guide to condition...

+1..
If bearings are scored, but crankshaft is OK, you may get away with replacing bearings only.
Hope you are OK...





Beware of what you wish.. for it may come true....

I have decided to use my other block to save time, i have noticed it has some pitting where the triangle sections of the gasket have sat, will it be ok? i think those bits will be cut off by the new gasket anyway, you can see where i have drawn around the areas

Those areas wont matter. You need good surface around cylinder bores, water and oil ways.

Dont forget to prime oil pump by packing it with vaseline (will disolve in oil, other grease wont) and check oil appearing at top of engine.

Re other engine, without taking head, crank and rods off, it is anyones guess what damage was done.

As others have suggested, drive it until it dies, keeping eye on oil pressure, oil consumption and knocking noises. A compression test would tell you if bores are knackered.
