I have read to remove the transmission, the engine has to be lowered enough to allow the trans to come out. Does the motor mounts have to be loosened to do this? I have the trans completely disconnected and my engine is being supported at the oil pan by a stand and block of wood. I have also unbolted the bell housing. Car is on a mid-rise lift. I have a new Steeroids steering rack installed. Looks like there is not much space to allow the engine to be lowered. Maybe I'm just paranoid!!! Any suggestions? Seems like I am right there, but just not over the hump.
You need to remove the shifter assy and rods. This will give you enough room to pull the trasmission back and rotate it 90* degrees to get the input shaft past the bell housing. When I did mine I left the bell housing attached to the engine until I got the tranny out.
Also, I had a small jack under the oil pan to raise or lower the engine as needed. I disconnected the tach cable at the distributor, removed the ignition shielding box, and removed the fan so it wouldn't hit the radiator shroud whiile being lowered. I did not loosen the motor mounts. The rear of the engine only needed to be tipped up or down an inch or so.
When I said disconnected, I mean that there is nothing attached to the transmission. I have it completely separated from the car where I can move it around. Turning it on its side...etc. I have the exhaust off. All I have to do is just take it out. The only thing I have not done is lower the engine. I guess I will try that this weekend. The question I previously asked was should the motor mounts be loosened in order to tilt engine down?
I have never loosened the motor mounts. Just lower the jack that is holding up the back of the engine. That should give you just enough clearance for the input shaft of the tranny to clear the face of the bellhousing.

I've got to ask, did you completely disconnect the transmission from the bell housing? You're stating that nothing is attached to the transmission, but does that include the bellhousing? Because I found it to be nearly impossible, without disconnecting it from the bellhousing. If you have, then ignore this, just making sure.
PS, it's still a very tough wrestling match getting it out, that's for sure!!! WWF has nothing on us.

No need to loosen the motor mounts - the distributor will hit the firewall long before the motor mounts bind. Be careful not to let the distributor bind too hard against the firewall. You "should" be able to twist the transmission 90 degrees and have the input shaft clear the bell housing and drop forward after that. I have one 4sp where it doesn't clear the bell housing and I'm always forced to disconnect the bell housing and pull it out/down with the front of the transmission. Coming out not to bad - going back in like that takes extra set of hands.
see my pics. I dropped tranny and you can see I pulled motor with bell housing. I don't know I'd this helps or not.

I am going to be removing my trans in a few days. I am having a tough time removing the pipes, do they need to come out, or can it be done with them still installed

Removing the pipes (all of them) from the exhaust manifold to the mufflers gives you much more room to work.
Any tricks to get the joints apart? I will need to do this to remove the exhaust from the crossmember
Leave the front pipes bolted to the exhaust manifolds. Unbolt the rear pipes and mufflers. Have someone lay under the car and hold the front pipe just forward of the crossmember, you grab hold of the muffler/rear pipe and move it up/down, left/right, until you make enough play in it to pull it off. Pretty much caveman technology at its best. Then remove the front pipes.
