Hi, you could have the block linered, liner od is around 59 mm so you could not go back to 58 mm.
If you want the extra capacity get another block, if you are happy with 747 cc then liner back to standard, but would be more expensive than getting another block.
The fact that it is 58 mm is not indicative of it having Renault pistons,as you can get A7 ones that size.
The Renault rods have press fit small ends so unlikely the pins would have moved and scored the bore, only way to know for sure is to pull the block off.
I have Spare 58 mm block if you are interested. gene.h@hotmail.co.uk
