I've built a few engines and been involved in the SBF and SBC scene for a number of years.
It is quite easy to look up the dimensions for the engines being discussed.
The 6.2L Ford is physically huge. That's why it was never used in the Mustang, whilst the 4.6L, 5.0L and 5.4L have all been used.
The history of the engines is actually somewhat amusing. The original Modular was Hurricane (which later became BOSS after Katrina), which was a large OHC engine with a 4" bore like its Windsor predecessors. However, due to size restraints on the engine compartments Ford wanted to put it in (think the Lincoln Continental, which was FWD) the large engine wasn't going to fit. So, they came up with a physically smaller version of the engine by reducing bore spacing and diameter. This is what resulted in the 4.6L and later the taller decked 5.4L Ford. The 6.8L V10 also shares the same bore size and spacing as the other two. The bean counters didn't find it logical to manufacture two completely different engine families, both V8's, at the same time, particularly with the niche the larger family would fill, so the original Hurricane engine was just shelved.
Years later, Ford was looking at bringing back a larger displacement engine and so they resurrected the project. The result of this was that the 6.2L happened.
The 6.2L is in many ways similar to the old 427SOHC; it is basically a resurrection of that legendary engine. Deep breathing 2-valve heads with overhead camshafts and large bores. It had the potential to be a very potent engine. The problem is that it is very large and subsequently not practical to put in something small like the Mustang.
Ford figured out to put a Boss 429 into the 1969 Mustang way back when, somebody's going to figure out how to put a Boss 6.2 into a late-model Mustang. Hotrodder's are funny that way!
The 427 Cammer is one of my favorite Ford engines, and I can see that the 6.2 is fairly close to its design concept and dimensions. The 427 had a bore spacing of 4.625", which is fairly close to the 4.53 of the 6.2. If Ford really wanted to stretch it, they could get a 4.25" bore in it.
When I was working at Eaton, we would call on Ford in Dearborn, and they had a racing version of the 6.2 in their lobby. The sign on it said it was making 700+ HP. It looked like a cobbled together development piece, with external dry-sump pumps and fabricated aluminum valve covers and intake manifold. The sign didn't say what displacement it was.
