Is the 383 a better engine, or does the 440 just have more displacement?

One reason why I'm not ready for a stroker engine and many other's too is the rest of the driveline needs to be built much stronger to handle the monster torque. Rear end if it's a 8 3/4 needs to be beefed up, driveshaft needs to be upgraded, transmission etc don't just throw stroker in front of stock parts it won't end well.
A 383 or 440 you can make these parts live.
Does someone make a Dana that is designed to bolt right into an A body? That would certainly make that part easier. Plus, you could recover a good chunk of your Dana investment by having an A Body 8.75 to sell. And if it was in good shape with Posi-traction (just kidding, I meant Sure Grip), it would be worth even more.
