Big Bore Details | Ford's Godzilla (7X) V8 Engine | Plus a New Name
Ford_7X_P4_004.jpg

In our previous Ford 7X Engine Article we mentioned that we have a bit more insider information to share. While this some of this info is single source, I have been able to confirm a good deal of it as completely accurate. I am 100% certain that the engine is a 2-Valve Pushrod V8 with Aluminum Cylinder Heads. They will carry on with the Ford tradition of being clamped to the block with 4 Bolts around each cylinder. It is going to be direct injected, and it will be built at Ford’s Windsor, ON Canada Engine Plant.

The 7X's rocker mounts are very similar to those found on this GM head. Though the Ford castings appear more intricately yet robustly designed.

But wait, there’s more. We’ve also received some information about the engine block. While I can’t confirm these figures at this time we have been told that the Godzilla V8 has a 4.11-Inch Bore. With the help of a little 4th Grade math (V=π r² h, solving for h) and working backwards from that figure and the displacement we calculated that ‘Zilla should have a 4.19-Inch Stroke. That’s pretty much a square engine, which would make it very “trucky”.

This is the 6.2L Ford V8. As you can see, the iron block is quite beefy.

We’ve also been told that the 7X Engine Block will have a 4.527-Inch Bore Spacing. Coincidentally, that figure is identical to the outgoing SOHC 6.2L Boss/Hurricane V8. Considering that the 6.2L, found in the 1st Generation SVT F-150 Raptor, had a 4.015-Inch Bore and a 3.740-Inch Stroke it would appear that Godzilla can be seen as a Stroked and Poked Boss. It makes financial sense to utilize engineering, and possibly tooling, that has already been paid for. Being that cost savings appears to be a driving factor in the Godzilla Engine Program, I would have to say that all that inside info seems plausible.

The 7X heads are a good deal more compact that the SOHC ones found on the 6.2L.

With the Bore Spacing being over 4.5-Inches I believe it would be safe to call this engine something other than a Small Block (perhaps M/S Block?). GM’s LS/LT engines feature a 4.4-Inch Bore Spacing, and the Mopar HEMI Series rings in at 4.46-Inches. So Godzilla appears to be a shade larger than both of those, not to mention the Modular Series’ puny 3.937-Inch Bore Spacing. Big Blocks typically come in around 4.8 inches, so it definitely looks like we’re not getting a new generation of BBF v8.

This is the GM LT-Series DI-V8. It will be interesting to see how similar the finished 7X will look.

Word also has that the block will feature Cross-Bolted Main bearing Caps, which is another 6.2L V8 feature. To be fair, Ford has been almost exclusively building Deep-Skirt Cross-Bolted blocks for nearly 30-years (the 2.7L EcoBoost is a significant outlier). I grew up wanting basically anything powered by a 427 SOHC Big-Block, and there’s a possibility that I may be able to piece together and odd-ball modern version of it. But that is a story for another time.

It seems to be nearly a certainty that Godzilla will have a deep-skirt cross-bolted-main block like other Ford engines.

Now for, let’s engage in a little speculation on compression ratios. The F-150’s 5.0 Coyote V8, which features both Port and Direct Fuel Injection systems, comes in with 12:1 compression. That seems to be a trend among manufactures of DI NA-Engines, as most seem to be right around 12:1. It’s probably safe to assume that the 7X will be something close to that, or possibly a bit lower. Engines designed to work hard tend to have slightly lower compression ratios to lower cylinder pressures and increase longevity. However, with advancements in technology (fuel and ignition control) and materials (ring, bearings, and pistons) this trend seems to be giving way to more squeeze.

Get ready for more compression. The 7.3L is going to be several points higher than the outgoing 6.2L.

Finally, according to our source the final displacement of the engine will not be the familiar 444 Cubic Inches from the Legendary 7.3L Powerstroke (also known as the International DT-444E) of years gone-by. Instead, this all Ford V8 will displace 445 Cubic Inches. Considering where Godzilla is going to be built perhaps we should start calling it the 445 Windsor?

I'm hoping the 7X will keep the piston oil squirters found in the 6.2L Boss/Hurricane V8 and the 6.7L Powerstroke Diesel.

We are still working to gather more information, particularly about the block and crank materials. I have a feeling, given the industrial nature of this engine, that we’ll be seeing a Cast Iron block and a Cast Crank. Considering every other engine Ford produces it is almost a certainty that it will have Cast Pistons and Powdered Metal Rods. That doesn’t necessarily mean doom and gloom, as Ford has essentially perfected the use of those economical materials during the nearly 30 Year run of the Modular Engine Series. As soon as we have more concrete information to share you’ll find it right here on SVTP.
