Would it be any more or less correct on a COPO than a 425 HP CE coded motor?

[/ QUOTE ]Personally I'd consider it to be "less correct" if there is such a thing. Technically, a CE block could have been installed at a dealer under warranty, so a CE would make sense being in say a '69 COPO Camaro or Chevelle, however, under no circumstances would it make sense for a passenger car (Impala, Biscayne, Caprice, etc.) coded 427 block to be installed in a Camaro or Chevelle, unless it was pirated from the said passenger car and installed by a shade tree mechanic. But then again, there's only one engine a given car can have to be "THE original engine" and that's the very one it left the factory with. Anything else is just a NOM. A CE block that was dealer installed with the paperwork to back it up would be be the best NOM to have IMO.
