Make Your Cummins 12-Valve Swap Easy by Using Our SoloSwap® Mock Up Block
There's nothing wrong with taking the easy road with an LS swap or repowering your ride with a factory engine that was simply not offered in your ride when it was originally produced. That said, engine swaps of a unique nature of have really grown in the last few years. One such swap we've seen on the SEMA show floor and slowly make its way to both drag racing and in building something different to cruise in has been the famed Cummins engine swap. This 5.9L inline-six diesel engine has been found in the first and second gen Dodge Ram pickups from 1989-1993 and 1994-1998, respectively. The deep skirt block and beefy internals means this engine can take a ton of boost. We've seen the early 12-valve 6BT Cummins under the hood of everything from muscle cars and pickups to dragster chassis.
It may sound strange to consider an inline-six diesel truck engine for your next build, but we have to say, the aftermarket support for these 6BT 12-valve engines is quite large and still strong to this day. This shows the immense popularity and potential of these Cummins 12-valve engines. Not to mention if you're looking for something that can deliver massive amounts of torque at low rpm, then the diesel world is the world you want to live in. The square body Cummins swap is become quite popular due to the ease of fitment and the torque capabilities of this diesel conversion.
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 over 800 plus pounds of dressed Cummins 6BT 12-valve 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 heavy Cummins diesel conversion donor engine in your project, and that is with the Speedway Motors patent pending SoloSwap® steel Cummins 6BT 12V engine block mock up tool.
Laser Cut Steel Plate for Strength, Simplicity, and Easy Storage
Even if you have your Cummins 6BT engine swap donor all apart down to the bare block, that bare casting is still nearly five hundred pounds alone to try and roughly move into place to figure out your engine mounts, oil pan clearance, and more on your project. Using replica engines to mock up your 6BT swap for your project is much safer and your back will thank you for your efforts. We designed our 12-valve Cummins block mock up tool around the 1989-1998 12-valve production years, but the short block is identical between the 12-valve and later 24-valve head. This means that if you're looking to do a 24-valve swap you can still use our Cummins 6BT short block offering with your production 24-valve head mounted to it for mock up purposes.
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 a long tube header 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® Cummins 6BT 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® Cummins 6BT mock up engine block, which is available in 6BT short block and 6BT 12V 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 Cummins 6BT mock up engine block weighs in at just 31 pounds for the short block and 46 pounds for the Cummins 12-valve 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 head mimics the early 12-valve Cummins block models, providing mounting locations for your intake plate, exhaust manifold or header, and even the distinctive individual valve covers so you can quickly confirm if you'll have any fitment issues in your engine compartment.
This allows the complete mockup of an assembled and dressed engine, right down to your choice of stock or aftermarket components 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, water pump, and accessory brackets to our mock up block easily. The transmission bolt pattern supports both factory auto and manual transmissions (or aftermarket transmissions with the proper adapter).
Replicates Popular Cummins 6BT 12-Valve Engine for Mock Up Test Fitting
We did all the homework for you when designing our new steel SoloSwap® Cummins 6BT mock up engine block assembly. We have provided all mounting holes to replicate the engine block and head of the 1989-1998 Cummins 6BT 12-valve engine and other aftermarket crate engine offerings based on the OEM engine block. This engine was used exclusively in the 1st and 2nd generation Dodge Ram, however as an agricultural engine you may find it used elsewhere in agricultural equipment as well as medium and heavy duty trucks and buses.
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 Cummins engine swap in your home garage, or your hot rod shop is looking for an easier way to make 12-vave Cummins block swaps happen in customer's cars, our SoloSwap® bolt together steel Cummins 6BT mock up engine block will help you get the job done safely and quickly.
