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.


Wouldn't decking the block take the numbers off?


Yep, that is a big problem with the high dollar Chevy blocks. 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.
