Hy stephan, youre pretty much on track. it all should bolt right in as long as the motor mounts are in the same locations.
The reason you have to change bell housings is because the trucks used a different bellhousing than the cars, mainly to fit the vehicle. there were also differences in clutches and clutch forks as well.
I think the main difference between the truck and the car engine, is the truck engine is built for hauling and has different torque compared to the car engine.
