340 vs 360 confirmation

AJ/FormS said
a 360 in an A-Body was born peppy, and doesn't need much help.
A Magnum needs even less.

But if a rebuild is scheduled, the LA can easily sneak up on the Magnum.

A rebuild is definitely on the list. I have no idea what the previous owner did or didn't do, so I'm erring on the side of caution.
