Identical? IDK for sure. There may be a hole or 2 that aren't the same. Beyond that, they're similar enough that the parts will swap over & no reason to swap x-members unless the 'new' unit is freshly painted/detailed.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
