For Ford Salesmen Only: 1963 Ford 427 High Performance Engines

1963 Ford 427 High-Performance Engine Sales ManualIn 1963, Ford provided its salesmen with this confidential booklet in order to give them the information they needed to sell Ford’s line of 427 high-performance engines.

The booklet includes details of the 427 high-performance engine line, suggested sales prospects and selling techniques, and, most importantly, specifications for the engines.

Whether you’re running a 427 in one of your rides or not, the booklet serves as a fascinating behind-the-curtain glimpse into Ford’s approach to marketing the venerable 427 as well as an intriguing view of a time when gas was cheap and size–in cubic inches–definitely mattered.

The Ford 427 High-Performance Engines booklet is the first of what we at Classic Cougar Community hope will be many more offerings of manuals, literature, and other media contributed by the Community.

The 1963 Ford 427 High-Performance Engines booklet was provided by Royce Peterson, and is used with his permission. Thanks, Royce!

427 Engines

Cylinder heads used on the W-code 427 through (about) mid-to-late Jan 1968 were casting # C8AE-6090-J and are supposedly the most difficult to find.

C8OE-6090-N cast heads were used after Ford ceased using the J heads.

Intake manifold casting is C7AE-9425-F. It is cast aluminum and also known as the Police Interceptor intake due to its use on thousands of Ford/Mercury 428 Police Interceptor engines.

The most prominent date for a production GT-E engine was July, 1967. There are some known originals from August and September of ’67. Certainly once you get into ’68 all the ones I’ve seen have been service replacements, rather than regular production.

All 427 side oilers made after about June 1967 were drilled for hydraulic lifters.
