IO-470 with 520 bore

Post by Scandinaviansky » Tue Apr 24, 2018 3:02 am

We have bought a plane with a IO-470 modified with 520 cylinders. As far as I know is the P-Ponk conversion only for the O-470 not for the IO-470.

Does anybody know if this modification ( IO-470 with 520 bore) is common?

Thanks, Daniel

'Not common, but I know it's been done before.
