Here's what I found |

The 428 CJ came out after the 1968 shop manual was issued. Therefore the specs are not in the shop manual. Ford issued service bulletins in May 1968 detailing tune up specifications and other details specific to the 68 1/2 Cobra Jet cars such as the new 4 pinion 31 spline Traction Lock differential. Other topics included the starter delay unit and how to troubleshoot failure of that system.
The carburetor chart lists Holley 735 CFM carbs C80F-AA for manual trans cars and C80F-AB for automatic applications. Pump cam should be installed in position #2. Jetting is #66 primary and #79 secondary.
