That is the same route I took with my 1/2ton Cheby a couple of years ago. But it didn't have the mighty CUMMINS it only had a little 640ci 15:1 compression big block. Lots of HP but couldn't even touch my tow rigs (in sig) torque.
Back on subject: The super short box makes for excelent weight transfer.
Happy to see people stepping out there and pushing the limits. Even more so in a streetable truck.
Congrats guys.
