How to figure engine size?

I am buying a TA next week and it has some good amount of engine mods done to it. The owner said it was 422 CI, here are the specs I was given, does it figure out to be 422? Another person told me an iron block would do 422 but an aluminum block wouldnt?

Here are the specs, can someone do the math for me or tell me how to figure.

Rotating Assembly: Cola 4340 forged, 4" stroke. Rods:
Lunati Pro Billet Ultra light 6.125". Pistons: Ross forged 4.100" dont have the exact bore size.

Thanks guys!

Its either an iron block or a re-sleeved ls1/ls6 block

here is a calculator to play around with:
