Here is another very similar engine that is in the shop at the moment. This is another 1966 427 but the factory engine numbers are still on it so it can be decoded as a 1966 427/425 or a L72. The 427/425 had solid lifters, 780 Holley carb, a bunch of special parts and only came with a manual trans. This one came out of a passenger car but the VIN isn't stamped on it so don't know what. Probably Impala SS. The passenger car 427/425 are much rarer than the Corvette L72 engines since most people buying a big car didn't want a high compression, solid lifter engine with a manual shifter.
I think this one his getting hot rodded too but I don't know the details.

Corvette guy's don't care about the numbers on the block originally, they put them on during "restoration "

I thought VIN numbered blocks didn’t begin till 68, so a correctly dated 66 block could be called a numbers engine? Exactly, but a 1969 casting date block that you ground off the VIN that started JS27R0B would never be correct, but the guy did it. The VIN pad on the oil plan rail didn't even exist on Hemi blocks (or big blocks) till 68.
Kayse can't keep up at all now. lol

Lots of blocks lost their VIN numbers during rebuilds back in the 70's and 80's. Eventually people figured out to leave the VIN area unmachined but that requires modern equipment. The old surfacing equipment used 40 years ago just did a complete pass and the VIN number and engine ID was destroyed.

They started on corvettes in 1960 Yeah I've seen some mention of that. Sounds like GM only stamped the VIN on special combinations and even a 427/425 Impala SS wasn't special enough to get a VIN stamp in '66. Without a VIN we're just guessing on the Impala SS. Could also be a Biscayne. No way to know at this point but it was a rare bird whatever it was.

Well, stamping Corvette blocks - or should I say re-stamping - to have the desired #s has been going on forever. Obviously, that usually requires decking, but it's been a refined art for some time... As has restamping Mopar blocks.................

That was not a mistake, that was owner stupidity.
I have seen it done to very collectable guns too.
The good thing about a block is it can be machined and corrected, whereas you don't mess with gun serials.
