Change the flywheel. The swingarm transaxle in the 1967 requires a 180mm flywheel; the independent rear suspension transaxle in the 1976 requires a 200mm flywheel. Then steal the cooling tin off the 76 engine, because it's way different. Other than that, it should go right in.
electronic fuel injected motor. as opposed to carburated
You have to get a special intake that you can bolt a carburetor to.
fuel injection
That should be throttle body fuel injected.
If it is a stock engine; or if when you look at the engine, there is a large, round air cleaner on top of it, then it is carbureted, not fuel injected If it is a Wagoneer then it is fuel injected in 87. If it is a Grand Wagoneer then it is carburated.
It is possible.
If it's fuel injected, inside the tank. Carburated, attached to the engine block.
If it's fuel injected it's in the gas tank and if it's carburated it's on the engine.
If it's carburated then 4 - 6.5psi fuel injected 9 -13psi when you turn key on with engine off
If it is fuel injected it is mounted on top and inside the fuel tank. If it is carburated then follow the fuel line to the engine and it will go right to the fuel pump mounted on the engine block.
an engin
Yes it can! A fuel injector is just an electic valve. The valve can can stick open and let too much fuel into the manifold. It can have excessive wear and leak even with the engine off. It is controlled by an electric signal from the computer and if the signal is wrong, it can send too much fuel into the engine. However, when you start the engine, if there is nothing wrong, pressing down on the gas pedal wont do anything to change the starting of the vehicle! Unlike the carburated engines, an injected engine wont need to have the choke set by pressing down on the pedal which also sprays fuel with the accelleration pump. So you can flood a carburated engine in a different manner than an injected engine.
