How to identify and verify V-8 drivetrain parts for small and big blocks on Chevrolet passenger cars from 1955-1959, including:

  • Series 150
  • Bel Air
  • Corvette
  • Series 210
  • El Camino
  • Impala

Based extensively upon original source materials from Chevrolet Archives

Chevrolet by the Numbers is the only authoritative reference for identifying and verifying the correct Chevrolet parts, by casting number, for your exact model.

  • Restoring your Chevrolet to original factory specifications? You'll find the casting numbers that correspond to your car's Vehicle Identification Number. With this correct information you will avoid buying - and being sold - the wrong parts.
  • Buying a Chevrolet that has been restored? These numbers will help you determine whether or not the car has been authentically restored, and whether it's a smart investment.
  • Searching for factory high-performance parts at swap meets? Chevrolet by the Numbers tells you which parts to look for, why they are special, and which engines those parts came with.

Other books rely on secondhand information or out-of-date part numbers. Author Alan Colvin documented every casting number for every Chevrolet V-8 engine and drivetrain part from 1955 through 1975, using original source material in Chevrolet's archives, including engineering blueprints, technical service bulletins, and build sheets. He interviewed the original manufacturers and engineers and brings you fascinating stories of parts development from behind the factory gates. Most of this information has never before been seen in public.

Engines covered:

  • 265
  • 283
  • 348

If you absolutely want to know the original part numbers for your Chevrolet drivetrain - not just what interchanges or fits - but the correct part that came with your car when it rolled off the assembly line - Chevrolet By The Numbers has the answer.
