Two, A V-8 means that in theory looking at it from the front, it looks like a V. Each side has a bank of 4 cylinders, Each bank has an exhaust manifold equaling one on each side.
On a V8 engine there is ( 1 intake manifold and 2 exhaust manifolds )
between the exhaust manifold and catalitic converter
On a 2004 Lincoln LS ( 3.0L V6 and 3.9L V8 engines ) Each of the engines has ( 2 ) exhaust manifolds They are located on each side of the engine , on the sides of the cylinder heads ( there is an exhaust manifold gasket , then the manifold , and they have a heat shield over the manifold ) Your vehicle exhaust system connects to the manifolds
under the exhaust manifold on the passenger side towards back of engine
The engine will have one exhaust manifold attached to each "bank" of cylinders. In a v6 or v8, there would be an exhaust manifold on each side of the 'V'. With the transverse mounting of the front wheel drive, the manifolds are at the front and back of the engine. On a 4 cylinder, there's only 1 bank, so just one exhaust manifold. (NOTE: there hasn't been a 4 cylinder Taurus since 1986) On the front and back of the engine it will have three pipes coming out of the engine that turn into one pipe that goes all the way back to the muffler
Standing in the front of the engine it will be on the left front side of the engine up by the front of the valve cover. It will have a medal line coming from the bottom of it and going to the exhaust manifold.
true dual exhaust would mean that each pipe would be atached to an exhaust manifold of its own. It might be a v6 or v8 or as in the old days an inline 6 whith a split manifold was popular.
They have a straight six cylinder engine in them. Since the cylinders are all in a straight line (i.e. "Straight Six") the exhaust can by carried via the exhaust manifold through a (basically) straight pipe to the rear of the vehicle. With a V8 or V6 engine the cylinders are arranged in either two banks of 3 or 4 cylinders, one bank on each side of the engine, hence requiring and exhaust manifold and pipe on each side of the engine to route the exhaust gas to the rear of the vehicle.
Underneath air intake manifold on top of the engine.
That is the intake manifold casting number from a 1970 350 CI 300 HP engine.
The old exhaust manifold will need to be removed. The new headers will either have to be made to fit the engine well, or the inner fenders will have to be modified to fit. Then the headers will need to be either mated to the old exhaust or a new exhaust system will need to be installed. In a v8 engine installation most people prefer a dual exhaust to maximize the headers capability.
Yes , it is a V8 engine , so it has 2 exhaust manifolds , 1 on each side of the engine
