On the money Jeremiah.......no pun intended
Actually to build a Duramax SUV "cost effectively" meaning being able to get your money back out later down the road, (in case anyone reading this is up to the challenge), you need to work off of good condition used hardware. Remember a Dmax well maintained is easily a 500K motor and the Ally is a 250K unit hands down, so starting at 50-100K is just scratching the surface.
This is my price new from GM
Engine, siverado, sierra - 8 cylinder - 6.6l diesel - 8 CYLINDER - 6.6L DIESEL
Does Not Include: Water Pump, Torsional Damper, Intake And Exhaust Manifolds, Distributor, Flywheel And Clutch Housing.
Transmission siverado, sierra - 8 cylinder - 6.6l diesel-LCT1000-6spd-4x4
07-10 $ 3795.25
Transfer case, silverado, sierra, 6.6l, w/electric shift
We are at 13K (with my 30% dealer discount) with no shipping and no hardware, building new would drive a build well into the 30K range and just isn't cost effective.
Never throw good money at bad, you won't get it back, Just my finding in the business.
