Hello everyone! I'm back to work on my coach, after an eternity of not doing anything to it for lack of time and money...
OK, so it's time for me to do get my engine + transmission back in the coach...
I have lifted the front by the required 36" so that the whole thing would roll under on its little chariot, it's there now (front still in the air, secured on very sturdy cribbing). I have installed double chains front and back, with grade 5 bolts in the holes at the front and back of the heads. 2 chain hoists, one to the front chains and one to the back chains.
My problem is that when I lift the thing, it turns counterclockwise, the more so as I lift the front, and it basically wedges itself shortly after I clear the front crossmember with the pulley, at a 45% angle or so to what it should be.
Any hints as to how to better guide it in? This weekend I am going to try and position the hooks on the chains to that the front hook is more to the left, and the back hook is more to the right, and hope that this will do it.
I should add that the front axles are still in there, but that didn't keep the thing from coming out the same way I am trying to get it back in...
I would certainly welcome any advice/opinions on the matter!

Denis,
When I removed, installed, and removed the 455+trans+FD, I didn't notice the
thing trying to do an aileron roll. But today when we installed the Cad
500, we had a good bit of trouble with that (made me especially glad I
designed an new front motor mount with the rubber Olds mount shifted toward
the driver's side).
I can only conclude that during previous R&R's we had the hooks on the
chains (attached much as you describe) tighter on the driver's side. I'm
thinking that it might be smart to use lifting rings at the dead centers of
the chains, then do test lifts and adjust chain lengths to eliminate the
roll. IF I ever have to do it again (sure hope not).

engines always twist a little, i usually just push on them to straighten them out.
yes sometimes I'm lifting with one hand and pushing with the other hand...or foot

I got my engine+transmission in! Very exciting. I followed your suggestions, Ken, and played with the hook locations on the chains until I hit the sweet spot. It took quite a few tries, but eventually the thing lifted more or less straight, and the front engine mount ended up amazingly close to where it should be. A little shoving here and there with a 2x4 and the mount bolts went in! Happy time.
The rear transmission bolts were predictably hard to install. I got things started by installing a slightly undersize stud in the driver's size bolt hole of the transmission (the only one that is pass through) which helped do the first location (much careful lifting and lowering and shoving to and fro to get it to engage), then I was able to install the upper passenger side bolt, then the driver's side.
Then I tried the lower passenger's side bolt and this is when I discovered that this hole was at least probably a little bit stripped - the bolt was difficult to get in any way I tried - and I ended up stripping it some more. I stopped when I realized that it was quite hard to wrench it in further, and I was far from all the way in.
Dang.
Has anyone ever done that? The thread is not stripped to the point where it won't grab, but it is definitely deformed - not too far into the thread, thank heaven. I am thinking of trying to fix up the bolt hole in place, with a tap - I *really* don't want to take this whole thing out again!

Yes! I would make sure tap was straight and go for it.
Good Luck.
