For the regular classes, I think that Chevrolet has done a very good job of looking after the older N/A combinations. |

Re: 2014 COPO Engines
the 450 is a .100 stroked 427, same bore od 4.125, with mechanical roller lifters and they must have changed the head because there is a different part number. Fun to own one. Dyno

Re: 2014 COPO Engines
Different piston config, more cam, more intake runner volume, bigger valves, more rocker ratio, etc. About the only thing you can use from a 427 are the rods, the manifold and throttle body, and the block.

Nope...same exact block with a 4.200 arm, and the manifold and throttle body are exactly the same as the 12 and 13 427's.
