Save Time Mocking Up Your Godzilla V8 Using Our SoloSwap® Mock Up Block

As Ford's replacement for the aging Modular 6.8L V10 SOHC engine used in Super Duty trucks, the 7.3L Godzilla engine, a clean sheet pushrod design that shocked Ford enthusiasts, debuted in the 2020 F-250 and higher Super Duty pickups. With over 20 years of Modular engine production and Ford's Coyote engine, which debuted in 2011, being one of the hottest "Ford in a Ford" engine swap ideas, the new Ford Godzilla engine has quickly become swap fodder for many Ford enthusiasts. It's not terribly hard to find a wrecked Super Duty in the salvage yard and Ford Performance and others are even offering Godzilla-based performance crate engines. Meanwhile, you can find swap mounts, accessory drives, and more to make your Godzilla swap a near bolt-in if you have a popular chassis like a Fox Body Mustang. But what if you're trying to fit your Ford Godzilla engine swap into an early Maverick, or maybe even a classic F-100 pickup?

Traditionally, building something with an engine that was never meant to be installed in it would require an engine hoist, an actual engine, and a spotter or two keeping things in check while measurements were taken, parts tack welded, and so forth. It's not an easy or quick process, as the engine must go in and out of the engine compartment numerous times. It can be dangerous with a 500 plus pound Ford Godzilla engine dangling on a chain over your hands (or head!). While this may have been how your father did engine swaps in the past, there is a better, and safer way to mock up that Ford Super Duty donor engine in your project, and that is with the Speedway Motors patent pending SoloSwap® steel Godzilla mock up engine block.

Laser Cut Steel Plate for Strength, Simplicity, and Easy Storage

Even if you have your Ford Godzilla engine swap donor all apart down to the bare block, that bare casting is still over two hundred pounds alone to try and roughly move into place to figure out your engine mounts, headers, and more on your project. Using replica engines to mock up your 7.3 Godzilla swap for your project is much safer and your back will thank you for your efforts.

Past mock up options included a plastic engine block or foam engine block, which, while being light and easy to maneuver, these plastic engines often did not hold up well to repeated usage or the installation of heavy components like long tube headers or a turbo manifold with turbo bolted to it. They're also not the best option when localized welding and grinding is happening to fab engine mounts/brackets either. Plastic blocks can easily be damaged from grinding or welding sparks. This is why we designed our SoloSwap® Godzilla mock up block system from laser cut 12-gauge steel with all accessory mounting holes accessible from the back side for simple "nut and bolt" assembly of your accessories for engine mock up. No more thread inserts that work their way out of the foam engine block material or even needing the factory hardware during the mock up phase. Just grab yourself any fastener of the proper length and diameter to install your headers, for example, saving the good installation hardware for final assembly.

Available in Short Block or Long Block Configurations

Furthermore, our SoloSwap® Godzilla mock up engine block, which is available in short block and long block options, ships unassembled, saving you shipping costs and storage room when not in use. Simply assemble the mock up pieces following the provided instructions with the fasteners included and your mock up engine block is ready to use in minutes. Our steel mock up block can also be easily disassembled for storage, unlike some steel mock up blocks that utilize folding tabs. Once those tabs are bent over the block stays assembled, taking up much more room. Store your disassembled mock up block wherever it will easily fit, such as under a workbench, on a shelf, or other location that a full size plastic engine block or real engine block wouldn't fit or have the weight capacity to handle (ever try storing a real engine block on a plastic shelf?).

Our SoloSwap® steel Godzilla mock up engine block weighs in at just 27 pounds for the short block and 47 pounds for the long block, making it easy to handle and position all by yourself safely in the engine bay of your project. If you opt for the long block version the included 12-gauge steel cylinder heads provide mounting locations for your intake manifold, exhaust manifolds or headers, and even your valve covers so you can quickly confirm if you'll have any fitment issues in your engine compartment, though the Godzilla pushrod engine is not that much larger than a standard 351W small-block Ford and obviously narrower than the super-wide DOHC Coyote V8.

This allows the complete mockup of an assembled and dressed engine, right down to your choice of valve covers, heads, and more to confirm fitment, clearances, plumbing, wire routing, and so much more easily. Even if you're just using the short block, you can confirm fitment and engine location by mounting the oil pan, timing cover, water pump, and accessory brackets to our mock up block easily. Ford's Godzilla V8, both the original 7.3 and later 6.8 versions, use the same transmission bolt pattern as Ford's Modular and Coyote engines, and as used on our Coyote mock up engine SoloSwap® mock up block too. The SoloSwap® short block also accepts all stock and aftermarket Godzilla cylinder heads as well, so feel free to bolt up your actual cylinder heads for your mock up duties if you like!

Replicates Popular Ford 7.3 Godzilla Super Duty Engines for Mock Up Test Fitting

We did all the homework for you when designing our new steel SoloSwap® Godzilla mock up engine block assembly. We have provided all mounting holes to replicate the engine block and heads of the 2020 to current Godzilla engines used in the Ford Super Duty trucks, including the F-250, 350, 450, 550, 650 and 750; 2021 to current E-Series cutaway vans like the E-350 and E-450 (used for cargo vans, motorhomes, ambulances, etc.), and of course Ford Performance and other Ford Godzilla crate engine offerings based on the OEM engine block. The 6.8L Godzilla, found in 2023 to current F-250 and F-350 with XL trim package, is essentially a de-stroked 7.3 Godzilla, and as such, our SoloSwap® Godzilla mock up block will function as a mock up tool for these engines as well.

Now you can quickly and easily confirm you have enough clearance for radiator cooling fans, power steering rack, fluid reservoirs, and other items commonly found at the front of the engine compartment. So, whether you plan for a sole 7.3 Godzilla swap in your home garage, or your hot rod shop is looking for an easier way to make Godzilla swaps happen in customer's cars, our SoloSwap® bolt together steel Godzilla mock up engine block will help you get the job done safely and quickly.
