Determining 1967 273 numbers matching?

The reality is that even having the "original" (or date correct) block/engine will add little to no value at the end of the day, maybe on a big block car. With a 273, down the road one would need to find a date correct block (2bbl & 4bbl are the same). On my recent build I didn't bother it has a 66 model year block in it.
