Why>? Putting the cam in the block and actuating the valves with pushrods (through rockers) works really well. The main advantage is that, especially in a V engine, there's only one camshaft. Also, the camshaft drive is a lot shorter which gives better accuracy in timing. Chevrolet stuck with the pushrod engine because they also tend to be smaller. There's no camshaft up above and no cam sprocket. On a V engine, that makes it both lower, narrower and lighter.
Technology is NOT always an improvement..DOHC and SOHC have their advantages..but tried and true muscle cars still use pushrods for a reason.
