I'm sure that Ford built this engine with reliability in mind because it's going in Super Duty trucks that are built for work. I'm sure they could have got more power out of this engine but at what cost. Would reliabilty be compromised? Would fuel economy be compromised? Just by looking at the specs it should be a joy to tow with unless you are pulling a very heavy load.

I like my 6.2 but I think the 7.3 is going to knock the socks off of it. The low rpm torque paired with a 10 speed should be a winner.

I would wager that this engine's power output is emissions limited or purposely limited to add power later. Looking at what this engine is made is made of, I don't see adding another 30-50 hp by removing much of the emissions tuning having any significant effect on longevity or fuel mileage. In fact, it may even increase fuel mileage by optimizing timing.

I have not seen pictures of the block yet to know it is open, semi-closed, or closed deck. It appears to be a closed deck from the pictures I have seen. If it is closed or even semi closed, then there is no doubt it can handle even more power with what the crank and pistons are made from. Closed deck blocks are mostly found on heavily boosted gas and diesel engines. Although most(if not all) push rod truck engines are also closed deck due to their configuration which leads to their reputation for longevity and durability. The 6.2L was closer to a semi-closed block with only the outside cylinders being closed.

I would call it a semi closed block similar to the 6.2, but with small slots between the cylinders for coolant flow.
