Cummins R2.8 GM Automatic:

Finally a real solution to the Cummins R2.8 GM automatic is here.  Quick Draw Brand has made a kit that is easy to install, cost effective, and works.  This is the complete crate engine from Cummins with the GM automatic adapter kit that works with the factory DOC filter.  It is the shortest solution on the market.  This adapter kit has 2 starter pockets so builder can install the starter on driver or passenger side.

You will receive the Cummins R2.8 Crate engine; new from Cummins Repower, and a QDB GM auto kit which turns the back of the Cummins R2.8 into a GM small block or LS.  The  TH400, TH350, 700R4, 4L80, Allison 1000, and 6L80e will bolt to this adapter.  This kit uses a factory Cummins flywheel /flexplate so no worries about welds coming apart.  Compare the price of this engine and adapter kit vs Cummins price on just the engine; you will find that packaging the parts in this kit makes the whole process easier and cheaper.  This is not a complete installation kit but includes the most important parts to get your Cummins Diesel Conversion bolted together.  With the passenger side starter pocket used, this kit will fit in a vehicle with frame rails 30″ wide or wider, under 30″ the DOC will need relocated or the drivers side starter pocket will need used.  Some grinding to the bellhousing on the 6L80 will be required to fit.
