Engine and Adapter Package – Cummins R2.8 with GM Automatic Dual Starter Pocket Adapter


Cummins 2.8 crate engine PLUS Quick Draw R2.8 to Dual Pocket GM automatic Adapter



Finally a real solution for mating the Cummins R2.8 to GM automatic transmissions is here.  Quick Draw Brand has made a kit that is easy to install, cost effective, and works.  This package includes a complete crate engine from Cummins as well as the Quick Draw GM automatic adapter kit that works with the factory DOC filter.  Our R2.8-GM automatic adapter is the shortest solution on the market.  In addition, our adapter kit has two starter pockets that enable starter installation on the driver or passenger side of the vehicle.

Our Cummins R2.8 to GM automatic package is the most complete kit you will find. You will receive the Cummins R2.8 Crate engine, brand new from Cummins Repower. In addition we include the Quick Draw GM auto adapter kit, which effectively turns the back of the Cummins R2.8 into a GM small block or LS.  The Quick Draw adapter works with the  TH400, TH350, 700R4, 4L80, Allison 1000, and 6L80E transmissions.  The GM Automatic Adapter uses a factory Cummins flywheel /flexplate, so no worries about welds coming apart.  CCompare the price of this engine and adapter package vs. the price of just the Cummins R2.8 and  you will find that a complete package makes the whole process easier and cheaper.  This is not a complete installation kit (engine and transmission mounts are not included), but our package includes the most important parts to get your project bolted together. Utilizing the passenger side starter pocket will allow the package to fit in a vehicle with frame rails 30 inches apart or wider;  frame rails under 30 inches apart will require relocating the the DOC and utilizing the drivers side starter pocket. Note that some grinding to the bellhousing on the 6L80 will be required.
