The SOHC has always perplexed me - they went to all the trouble to switch to OHC, with all the added complexity and reliability issues of the chain drive system. And for all that they got 2 valves per cylinder, all in a line and perfectly parallel. I'm sure they got better port shapes, but in the end it makes 51.8 hp/liter.
The pushrod 3.0 has slightly angled valves, is massively simpler and makes 51.3 hp/liter. So basically the 4.0 SOHC horsepower improvement over the 3.0 is exactly in proportion to the displacement increase.
