For an example, my 1969 came from the factory as a 250 six cylinder. On the SPID sheet the Vin number has the letters CE which means it was born with the 250 six cylinder. I'm in the process of removing the 250 and installing 292. I have already drilled the holes below the C/10 emblem to install the 292 emblems. This is the same place that they were on the new 1969 that I bought in the fall of 1968. If it had came from the factory with the 292 it would have listed the engine as an option on the SPID, and the emblems would have been below the C/10 emblem as the one. I bought new.
