You have a point with the light duty having the same cab on dodge and gm, but it's typical for a super duty to weigh around 1000lbs more than an f150, this is likely the same for the 1500's vs the 2500's. Does the 1500 cab hold up the same with another 1000lbs trying to crush it?

I feel like there is a simpler solution to the V8 problem than people realize: a cross plane crank i4 Ecoboost. The sound of a V8, the performance close to a V8, with the emissions and fuel economy of an Ecoboost. For anyone curious, the Yamaha R1 and MT10 are perfect examples of a modern cross plane crank i4.

I apologize, Google was telling me the 6.2 has a 3.7 stroke not 3.74.

When I calculate with the 7.3's 4.22 bore and the 6.2's 3.7 stroke, I get almost exactly 414 cubic inches (414.00587)

The 6.2 and 7.3 have identical bore spacing; the 7.3 block is basically the 6.2 block with a cam and pushrods added to the valley and larger bores with a taller deck height. I'm almost praying that the 6.8 is actually the 6.2 block with the 7.3 bores (and not the 7.3 block with the 6.2 deck height) because a dohc 6.8 with the Coyote's tech could realistically make 600hp NA passing emissions while the 6.8 pushrod will barely break 500hp with emissions. IMO that barely beats the current 5.0 Coyote so is that even worth making?

Simple, it has the 6.2 stroke and the 7.3 bore, this lands at 6.8L
