Not unless it was swapped in. They didn't start using any sort of computerized engines until they introduced their Throttle Bottle Injection system the next model year (1987). If it has a carburetor, it's all mechanical.
YES it does.
no it had a computer controled quadajet
230 HP@3800 RPM
YES it will fit right in. But now hears the problem that you will have. The 91 is a fuel injected computer controlled engine and the 86 is not. Therefore you would need the entire wiring harness and computer plus the fuel pump that's in the 91 fuel tank. You will run into all kinds of problems trying to get the 91 engine to run in that 86 truck. It would be cheaper and easyer to get a carburatored engine and put it back in the 86 truck.
yes they are the same.
standing in the front of the engine, It will be on the left front bottom SIDE of the engine.
You can put that engine in a go-kart ,IF YOU KNOW WHAT YOU ARE DOING.But as far as a direct bolt in NO. You would have to USE the 2004 transmission, computer, Fuel pump, complete wiring harness for the engine and transmission. speed sensors and wiring harness among other things. It would be a costly project to start and to finish.
