Mike is right... it flat out sucks!

You'll have to release the engine mounts and push it up (pull if you have a cherry picker). In order to have clearance for the pan to come out. there will be 3 bolts you need to take out. One of them holds the end of the screen in and two of them will hold the pump in.

When I did my buddy's 351w we did the clutch and new injectors in the same weekend. Taking out the tranny for a inspection and replacing the clutch was a great idea because it allowed us a ton more room. We removed the fan and fan clutch and pulled the engine way up and out with a cherry picker. This allowed the pan to drop out without the oil pump and screen off. Just a min... I'll post a pic that should help you locate the bolts without the pan off.
