There’s also no provision for distributor or drive off the camshaft, maybe that shortens the length of the block….
Look at picture below, notice timing cover and water pump length

Going by online sources, the Godzilla tapes up very close to a traditional small-block Ford at 730mm long (timing cover to rear of block), 585mm wide (across valve covers) and 635mm high.

It’s roughly an inch narrower than a 351W and close to four inches narrower than a Coyote….

Yeah it looks pretty close length and width I think it's the height Boss wasn't sure about and going off the deck height it looks like it might be a smidgen taller than a 351 I'm not sure if that would fit in many Falcons without a bit of bonnet surgery?

I can't see how it could be an inch narrower than a 351 windsor if the Godzilla has a longer deck height? Are you comparing the width of the Cleveland with its 9.2 inch deck height?

But then the Godzilla is a full skirted block so that would move the crank centre line up in the block (compared to the 351) so that would make it sit lower in the chassis........interesting

That’s straight from the former Ford Program Director for the 7.3, Brian Wolfe who also has raced Windsors for years.
The engine was designed to be compact so it could fit in all perceived applications, it and the LS are reasonably close.

Oh well he would know.......I was just going off the measurements?

The official measurements I looked at indicated it was 5cm wider than a small block from rocker cover to rocker cover.

Hardly worth worrying about, but the dimensions are hard to nail down when you don't know if the 2 measurements you are comparing use the same points of reference. Any they rarely tell you what points they measured from either.

Fact is it fits very easily in a Foxbody, with dimensions close to a SBF, which means fitting in a Falcon won't be hard. That XA that was running one with the harrop blower that ran 8's fitted it all under the hood very easily.

Apologies, I was mistaken about width and length, here is the actual size from horses mouth

https://fordauthority.com/2020/02/fo...windsor-video/

Size data such as this is important data to be able to shoehorn a Godzilla under the hood of a project car or truck in the future. What they found was that the Godzilla engine is about 2.5 inches wider than the 351 Windsor. On the engine length measurement, the 7.3-liter V8 was about 1.25-inches longer. Those figures aren’t vastly different between the two.

So compared to a 429/460, that is a good reduction

I'd like to see a project putting Godzilla into a BA. I wonder how the would handle the transmission. I like the idea of a stock one for low down torque. I'm guessing if BA can fit a 3v then Goszilla would fit. The 3v is a wide motor.

Transmission is easy, as it uses the same bellhousing pattern as Modular and Coyote. So any 6R80 or 10R80 bolts up. And there are adaptors for TH400's and the like.

The blown XA uses a TH400.

That much power, you could use 2-speed powerglide.
30 years ago now but HG Monaro 383 ‘glide vs SLR Torana off the lights,
70 mph in 1st, Torana tried his best but fell back every gear change….

Basically if it could fit the 302, 4.6, 5.4, Coyote… it can fit the Godzilla.
