Just curious and bored anyone ever seen a 572 street legal 3rd gen? if there hasn't been one that's definitely on my list in the future when I'm an old geezer post some pics if you have seen one tho
Any 3rdgen with a BBC, regardless of size, is technically not street legal, as the BBC was never an OEM engine in one of those cars, or anything newer.
Now... the "street legal ones" as in, they have plates on them, I have seen in the generic sizes... 396, 454, 496.. not anything that big though.
Depends where you live. Some places don't care what engine is under the hood to be street legal. It depends on your local emission laws.
As for the swap, a 572 is a tall deck block. Although it can fit, there are a lot of clearance issues in the swap. The taller deck makes HVAC clearance very close. Off the shelf headers will not fit. It's hard enough getting headers to fit with a short deck block and heads with raised exhaust ports.
Anything is possible with enough time and money but don't expect it to be an easy, cheap swap. It's a lot easier to stick to a short deck block and making a 540, 555, 565.
If you want to use a tall deck, why stop at a 572. A 632 is the most common big engine now.
Without knowing exactly what the engine is, anyone with a BBC under the hood can tell you it's a 572 and you would have to believe them.

Tampering with emissions controls is a federal offense...just happens to be nobody to enforce them in many areas.
