Welcome to CHR!

I think that the “131446” is the serial number (matches the VIN of the original car)
Maybe it’s:
V = Flint
11=November
27 = 27th day
CHA = could be a lot of combinations. As mentioned, it could be a 1973 - 307, or it could be a 1975/1980 – 350, or a 1980/1988 – 305. This code was used in any number of Camaro, Monte Carlo, Biscayne, Bel Air, Impala, Caprice and possible a 1975 Corvette as well as some Pontiac, Buick and Oldsmobiles.

Do you have the complete engine? If it has the original manifold, a 2 barrel would make it a 307 from the F/X/B model cars, a 4 barrel could be a ’75 -350 Corvette or a 1980 305/350 from a Camaro or a Monte Carlo. If it’s TPI it is from a 1988 Firebird

Complicated to be sure – but the real question is what do you want to do with this engine? Pull a head and measure the bore (assuming its stock) and we can tell real quickly what you’ve got.
305 = 3.736"
307 = 3.875" (shared with the 283)
350 = 4.000"

Do you want to rebuild it for a particular car? It’s probably not the base you’d want to use for any significant build as 350 roller blocks are still pretty plentiful from boneyards. I wouldn't put a lot of money in any non-roller block.
