I've heard that engine called a 454, but as SoDak says a 427 would look the same from out side. Generally speaking, Chevy Engines in kits are really only divided into Big Block and Small Block, unless you are trying to replicate an Exact Engine. Then it is worth hunting down Tim Boyd's, excellent articles (in the other mag) on how to tell the various engines apart. Those articles will help you to build a specific engine for a specific car.
For General Shelf Building, I don't get too far in the weeds, as to what is what, per engine displacement.
