Hedd my 'other' A7 engines use SV Reliant Regal conrods and based on the number of them I've seen reamed out to 9/16" I reckon you can probably get away with it. So what I might do is just put these away until I need the relevant oversize for one of those.
The engine I'm building though will use standard A7 rods and I'm not really wanting a fundamental change of plan at this stage.
How I wish I had the kit to machine my own rods! Though I love the idea. As it happens I'm half way through designing a rod for another application and it would be too much to take on right now.
Likewise I don't have the means to machine the pistons and bush them myself. I've just been talking with my local engine recon shop and they have seen this many times, though not done it themselves. They would take on the job but it would be something like £40/ piston, which - as per Alan's observation - isn't really worth it under present circumstances.
