I owned a copy of Ed Staffel’s Chevrolet Small Block Parts Interchange Manual before joining the HMN staff, and I use it all the time – mostly to determine the identity of parts that I stumble across or to answer occasional small-block- parts-I.D.-related questions from readers.

It’s a good resource, and it must be a good seller for its publisher CarTech, because the company has reissued the book for 2010.

I can’t see many differences between the new book and my old copy – other than that the latest one is full-color throughout. So if you already own it, don’t feel like you have to drop $24.95 for a fresh copy.

If the book isn’t in your garage, you won’t be sorry you bought it the next time somebody offers you a free set of heads and you’re quickly able to determine that they’re off of a late ’70s 267/305 or a 1973 307 and can say, “uh…no thanks.”
