273 commando .040 over

As it states in the title .040 or bigger . I see 2bbl pistons on ebay . Are all commandos .030 over bore? We have two 273's and both are original you can tell they were never apart. Both are .030 over.

To the best of my knowledge, Chrysler never offered .030 pistons. They went from .020 to .040
Aftermarket had .030 replacement pistons.
