Hi Keith
Agree the first time removing the nose is a pain but if you have it off every couple of years it gets easier. Having the nose off means you are not climbing in and out of the cab every couple of minutes of course if two people are working on the truck that time would be reduced anyway.
Thinking back on it with Chevy engine in the end I think had to remove the oil pan and oil pump to get it out through the opening. But that was a lot of years ago now.
With all of the bolts cooperating it takes something like 5 hours to have the engine out of the truck working alone. Here is the link to the removal time lapse:

As I have said before the reason for me doing time lapse is so that the next time, I watch the time lapse and it cuts down on the relearning curve.
