1968 Shelby Manifolds
Each of the different 1968 Shelby models uses a different set of exhaust manifolds. I have also included information about the lift hooks. Engine lift hooks were used by the factory to install the motors and were left on the cars. They were bolted to the exhaust manifold and are frequently discarded during normal maintenance.
Here are the GT500 KR exhaust manifolds. They have a unique shape. This is an original set of 1968 manifolds. Later manifolds differ slightly and are fully interchangeable. All Cobra Jet manifolds are 2 1/4 inch diameter. If you have a clean set of manifolds you will find the casting date.
You may be surprised to know 1968 Cobra Jet cars used two small lift hooks. I commonly see the large hook used, but believe the factory didn't start using the larger lift hook until 1969.
The GT500 exhaust manifolds are standard 428 parts. These manifolds are 2 inch parts.
Even though the GT500 and the GT500 KR have the same sized engine, the lift hooks are considerably different.
These are the GT350 manifolds. They are the same as all 1968 302 engines. The size is 2 inch. The GT350 uses the same exhaust as the GT500s.
