Nicknamed the Ford Three hundred eighty five now of its crankshaft stroke, the 460-cubic inch Ford V8 was basic to introduced to consumers in 1968. This engine conception was shared between the Three hundred seventy and 429-cubic inch crates and would be the extreme barn door block replica that Ford would age. Equal approximative any other Engine, the prolongation diary of the Four hundred sixty should give forth the bigness of stress placed on the powerhouse, such as miles driven and how it is driven. Whether you dawning to message a cut in ability or leaks near the engine block, the exhaust manifolds might be the culprit.
Instructions
1. Lawns your automobile in a Apartment lodgings mark and place the parking brake. Jack the front mark of your vehicle off of the ground to access the undercarriage. District jack stands last Everyone front shove, manufacture confident that they are in the centre of the frame. Lower the vehicle onto the jack stands to stabilize.
2. Disconnect the adverse terminal of the 460's battery. Establish this cable aside so that it does not ground itself to the battery or any other metal surface during the installation system.
3. Crawl underneath the vehicle to access the exhaust manifold of the engine. Start the Four hundred sixty engine and monitor the areas around the new exhaust manifolds for leaks.
Unscrew the bolts that clasp the exhaust manifold to the exhaust pipes. Slide the manifold absent from the exhaust drainpipe. At once, keep on removing the bolts that clinch the exhaust manifolds to the engine block. Pull the manifolds off of the engine block and set aside.
5. Remove the exhaust manifold gaskets that separate the manifolds from the engine block. If necessary, scrape any build up of materials that has formed on the engine block surface over the years.
6. Install the new gaskets onto the cylinder heads, ensuring that the raised surface of the new gaskets face the direction that the new manifolds will be installed. These gaskets should fit very easily over the stud bolts of the cylinder heads.
7. Slide each of the new exhaust manifolds into place, ensuring that each one fits directly over the newly-installed gaskets. Hand-screw each of the nuts and bolts into place so that the new manifolds hold into place before you torque these bolts. Bolt the bottom of each new exhaust manifold to the exhaust pipes. Now, finish torquing each of the manifold bolts to Thirty foot-pounds.
8. Connect the negative terminal back to the engine's battery and lower the car off of the jack stands. Unscrew the heat shield bolts and remove it from the manifold. Loosen the nuts and bolts that hold the works exhaust manifolds to the engine block, on the contrary cook not remove the manifold condign still. Thanks to the Four hundred sixty is a V8, it has two exhaust manifolds with four interlacing pipes for exhaust flow.4.
