All 5.0 motors are built using the same basic components(block and heads) so if you strip the car engine down to the bare longblock all the truck specific parts will bolt right on. Those parts include the oilpan and pickup, complete intake and fuel rail, timing cover and water pump, accessory brackets, and the distributor if necessary. Note that if your truck has a distributor with the TFI module mounted on it then you can use the car distributor which is setup the same, and you want to use the car dizzy because it has a steel drive gear for the roller cam in that motor. If however your truck has a fender mounted TFI module you will have to pull the steel gear off the car distributor and press it on your truck dizzy.

With all that done the motor will bolt right in place of the old one using the existing flywheel or flexplate, and connect to the stock truck wiring harness, the only change necessary is to route the spark plug wires for the HO firing order. You can expect the motor to be a little softer at low rpms but it will have more midrange and top end power.
