Finaly ripped my Fiat Twink out yesterday to solve an oil pressure problem and re-build with Microsquirt but once I'd got the head off it looks like I have a crack in the cylinder bore I'll try to add a photo and link to it . Is the block now scrap ?
cracked bore !!!!

Do twins use liners? If so new liner if not its scrap

No I think it's a single casting

You may be able to have it welded and then rebored but need to find a specialist. May end up cheaper getting a new block.

Welding a cast block, not some thing I've heard of.

Have seen it done but its expensive and dependent on the quality of the repair and the skill of the bloke doing the work.
(Saw an XE block that had been repaired once and it was bloody awful )



Think i'd be looking for another block...

As I said it might not be cost effective.

Here's a link to a company that I just got from a google search

As others have said it may not be cost effective to get a liner put in if you can locate a decent S/H block. If not I would recommend taking the block to a decent engine reconditioning company and see what they say. I did once have a set of liners fitted to a classic Mini block that had had a load of other mods done to it because it was cheaper than having all the mods done on another block
