What the technical guide helps resolve
Anghel and Perkins distinguish cylinder heads, intake, exhaust manifolds, water pumps, ignition, carburetion and cooling hardware across the Cobra Jet years. Its component photos are a reference for shape and finish, not measured CAD.
1968 details to check
The guide lists C8OE-6090-N heads and distinguishes the early exhaust-manifold version from later revisions. Its carburetor chart separates the 1968 manual and automatic applications. Verify casting marks, dates and vehicle configuration together.
Shelby-specific evidence still matters
The BaT KR listing describes Le Mans-marked valve covers. Do not replace that Shelby evidence with a generic Mustang engine photograph. Our current model shows a representative installation, not an authenticated engine from a specific VIN.
A modern component can hide in a period-looking bay
Mecum explicitly discloses modern heads and electronic injection on its example. An air-cleaner housing can conceal those differences. Preserve the seller’s disclosure alongside the photograph rather than modeling everything visible as original.
