Engine Removal

What is the easiest / recommended way to remove the 273 V8 and manual gearbox from my 1965 Dart?

So far I have removed the carb (got it rebuilt by Woodruff), radiator, fan, battery mount, and alternator. The engine looks too wide to go down past the frame rails with the exhaust manifolds on, but it seems only 4 very LARGE bolts fasten the crossmember to the body. If I attempt to lift it out, up, will I have to remove the bonnet (I don't have a tilter, but have removed numerous engines without one)? The car also has functional A/C, which I was hoping I would not have to remove /discharge.

The plan is to change all external gaskets on the engine to stop oil leaks, and paint. Install a 4 speed 833 or 833OD instead of the 3 speed gearbox. Change from non-power to power steering, including column.
