273 to 318-interchangeable parts

[sas73]

Unfortunately, my 273 block has cracked and is no longer useable. I found a 318 block and want to use it. Other than new pistons and rings, what will I need to buy specific for the 318?
My main concerns are the things like:
Heads
Intake
Timing cover
Water pump
Exhaust manifold
Carburetor
Oil pan
Distributor
Crank
Connecting rods
Lifters

Look at the back of the crankshaft to make sure the torque converter hub hole is the same size. I am thinking this is correct and that is why the transmissions won't interchange so someone please chime in with the details.
