Hmmmn...OEM spec...or "looks the same and can bolt in"?
You can easily drop in a 540-555-565-582 cube engine based on a short deck aftermarket block.

Assuming you mean largest as a function of cubic inches, not horsepower:
The 427 that was available in the 1967 is a Chevy Mark IV engine, typically known as the Big Block or "Rat" engine, is a standard deck height engine. Any engine based on that, as said above, should be an easy bolt in, dependent upon using an intake that is not too tall.
I have doubts that a taller deck height of the same big block engine would fit, based on the intake gets taller with the taller deck height.
The LS engine series are small-block based and are frequently seen in mid-years as well.
No idea on non-Chevy engines, but you did say "largest Corvette engine."

Just be aware that GM Gen V and Gen VI big blocks do not have provisions for a mechanical fuel pump or clutch bellcrank ball stud. GMPP does sell a bracket that bolts to the bellhousing for the ball stud. Aftermarket blocks like World Castings Merlin will fit everything from a Mk. IV big block. OEM spec, you can drop in a 496 (.060 over, 4.25 stroke 454).
