Assuming your components are assembled and ready for install, it shouldn't be a big deal. If you have access to a lift it'll be easier. You can mate the trans to the motor, mount the motor and all front suspension stuff on the k member and lower the car and bolt that sucker up. Makes it a lot easier to put it all together that way. Rear end is pretty simple, and so is a drive shaft... All assuming you have a lift you can use.
