I don't know where the first one came from because it was replaced by a shop.
A primary limiting factor to the performance potential of the engine is an incredibly restrictive stock down-pipe. Although the connection is shiny, has no corrosion, sometimes it does not make connection. Pistons had an enlarged primary compression ring, added intermediate ring, an enlarged ring land and wrist pin, as well as an anodized piston face. This is the gauge connection on a 7. Other improvements included tweaks to the , and an upgraded oil-coolant heat exchanger. The engine had two displacements: 420 cubic inches 6.

The second is on the drivers side betwee … n the valve cover and the exhaust manifold close to the front of the motor. Further investigation showed that I had fuel into the injector pump but none at the injectors. It can be cut off and removed to marginally increase airflow to the engine, though a noticeable amount of intake noise will be present. A light tap to the injector pump housing apparently is what it took to unstick the fuel shut down solenoid inside. I hope you find my solution helpful and would like to know if you were successful with the repair. I am glad you found the problem and that the glowplugs helped even if it was not the root cause of your problem.
