Stop Fighting Your Engine Stand, Use Our BlockDock™ Adapter Plate to Make Mounting Your Mopar Small or Big Block Easy
If you’ve never had the fun of learning how to use an engine stand to mount a Mopar small block or big block engine, you’re in for some frustration. You see, the typical Portable Engine Stand is universal in design with four adjustable mounting ears to attach the engine block to the stand’s rotating head. This allows an engine stand to work, theoretically, with any engine block, from an old truck inline six to that modern overhead cam engine you’re swapping into your hot rod. The issue is those four mounting ears don’t always line up the best with the engine’s bellhousing bolt pattern for a secure and safe mounting solution. Or it throws the engine off balance, making it hard to rotate on the stand. Lastly, we’re always wasting time trying to find the correct length engine stand bolts to secure the engine to the stand (because the factory bellhousing bolts are often too short).
Our solution to this common problem is a BlockDock™ billet CNC machined aluminum plate with the full Dodge/Chrysler/Plymouth bellhousing pattern machined into it along with slotted mounting points to mate up to the typical four mounting ear slots on an engine stand. This saves the expense of buying a specific LA small block, B/RB big block, or Hemi engine stand by making the universal one you already own work for these applications, including the modern Gen III Hemi. We include 1.8-inch long tubular spacers to provide clearance for an installed flexplate or flywheel, and we include all necessary bellhousing bolts for the plate to attach to your Mopar’s engine as well as to mount the adapter to your stand, after removal of the stand’s mounting ears.
Storage is provided right on the plate itself with threaded holes for your engine stand bolts, so you’ll never waste time looking for your Mopar engine stand bolts ever again. Your engine will be safer installed with our plate between your stand and engine block. No more flexing or bent engine stand ears, no more only using three of your stand’s mounting ears because you can’t get them all lined up to your block’s bolt holes, and no more of your engine being “top heavy” on the stand, making it almost impossible to turn over. Our BlockDock™ Mopar engine stand mounting plate solves all these problems, making your engine stand safer to use and more secure. So, once you’ve determined The Toolbox: How To Lift An Engine for removal, our engine stand adapter will be ready to help you safely secure your Mopar engine to your engine stand.

Summary: I hate the arms on engine stands, especially when trying to hang big block Mopars. These plates make it so much easier to bolt an engine up. So good at the time of this writing 11/25/2025 I own two of them.
Yes, I recommend this product.
I would buy this product again. Rated by Drag racer on September 30, 2025
Summary: Mopar engines, especially Hemi, are bulky. The adapter plate helps to center the load and makes rotation easier, and safer.
Yes, I recommend this product.
Neat and Clean (mostly) Rated by TK on September 13, 2025
Summary: Took out most of the guesswork in bolting up my gen III Hemi to the stand. The only quirk I found is one of the included spacers will need a small relief cut into it to clear the bell housing pin on the driver's side and they don't include nuts and washers for the lower-most bolts.
Yes, I recommend this product.
Very good quality Rated by Chris on May 18, 2025
Summary: Part is currently supporting my 440. Bolts directly up to your engine stand once you remove the universal arms. Only part missing from my box is 2 nutz for the 2 larger bolts
Yes, I recommend this product.
Fantastic quality, excellent strength, not 100% universal Rated by Metalmanonline on March 16, 2025
Summary: Works perfectly except it doesn't 100% fit on my harbor freight engine stand as it is and would need a slight modification to work. It may be their stand and not this piece that is the issue, just something to consider for those purchasing it. Overall excellent quality and I would recommend to anyone looking for a safe and evenly balanced piece to bolt up a hemi on a stand.
Yes, I recommend this product.
