For the pump tube and O-ring, I unbolted the oil pan, be able to drop it ~ 3/4 inch and that gave me easier access and visibility to the tube.
Worked like a charm.
The only thing I wished I had done is use that chance to replace the rod bolts with Katech bolts and my shortblock wouldn't have grenaded (rod bolt failure after many 200 dry shot passes)

That's a question and not being sarcastic. From what I've read the bolt is a pain to get to but is that it? Is that one bolt keeping people from replacing parts while the engine is apart?

yeah the oil pump and chain swap definitely added a bunch of time while changing out the cam but with those stiff manley valvesprings i think it was more than worth it. that pickup tube bolt is a PITA but i just did like everyone else and stuffed a rag in there and pulled the bolt out easily everytime i dropped it. so do yourself a favor and do the pump and chain swap, you'll be happy you did later
