Disclaimer – Please Read Carefully
WARNING: Due to the nature of engine and transmission swaps, we cannot
guarantee fitment into your vehicle without having to make mild to extensive
modifications. This should be considered when starting your project. It is
highly recommended to take the time to research any potential issues you may
face prior to starting your build. There are numerous forums and websites that
can help and give insight into any potential issues involved in the project.
This project is not for a novice mechanic. If an individual is
not confident in performing such extensive vehicle modifications, Speed Gems
recommends finding a capable shop for assistance.
Prior to and during installation of your new Speed Gems Transmission Adapter
Kit, always ensure to:
- Clean everything, including all components and surfaces.
- Use proper torque and Loctite all bolts.
- Do not force anything and begin all bolts by hand before using any tools. This will prevent cross-threading.
Check all bolt clearances.
We try to make everything as simple as possible to help you, but the ultimate
responsibility for the assembly of the kit is up to the installer.
If you have any additional questions, please contact us by phone at

APPLICATION NOTES
This Packard Kit was developed using 288/327/359 Straight-8 engine information
from a 1952 Packard. Speed Gems does not make any claims that this kit will
fit pre-war engines. Please be aware that Packard also made a much larger
Straight-8 engine and this kit will not fit that engine.
This Packard Kit should work with any Chevrolet V8-style Automatic
Transmission having the smaller converter bolt circle.
INSTALLATION INSTRUCTIONS
-
After removing everything from the back of the Packard engine, ensure all mating surfaces are clean and remove any burrs or debris. Next, install the supplied Adapter Plate using the (6) 7/16-14 x 1-1/4 SHCS provided.
NOTE: The Adapter Plate will be a tight fit over the dowel pins. Ensure the dowels are in place and free of burrs before gently tapping it into place. This tight fit ensures that the plate is located correctly. -
Install the supplied Flexplate and Crank Spacer using the (6) 7/16-20 x 1 SHCS & (6) 7/16 Flat Washers provided.
-
Install the supplied Starter using the (2) 1/4-28 x 1-3/4 SHCS provided.
-
The Chevy Automatic Transmission can now be installed.
NOTE: Ensure that there is appx. 1/8” clearance between the existing
Torque Converter and the supplied Flexplate, once the Transmission is tight to
the adapter. This means that you should be able to move the Torque Converter
forward to the Flexplate by that distance.
If there is more distance than indicated, it could be a bad Crankshaft Thrust
Bearing.
