1970 Green Machine
This 1970 Regular Cab - Long Bed Chevrolet truck has been re-worked and rebuilt many times. Previously in some point of its life it was fitted with a late 90's VIN "R" L31 Gen1 Small block 'Vortec' 350 behind a NV4500 5 speed transmission and transfer case. Then it was rebuilt using a 5.9L Cummins 24valve inline six engine that was mated behind a NV5600 6 Speed transmission and universal transfercase. The 5.9L Cummins had a built P-pump conversion but sadly was not up to the task.
The present configuration of the 'Green Machine' started with its donor vehicle, a 2005 2500HD Chevrolet Suburban. It was purchased as a donor because of an accident. The cabin of the Suburban was totaled, so the cab was removed to be recycled thus leaving nothing behind but a Independant-front-end, modern heavy duty frame with a complete drivetrain.

496 Cubic Inches
Numbers aren't everything, but with 8.1 liters of displacement and a 500 ft/lbs flat torque curve displacement sure is. The new generation big block 496 is a hybrid breed of Gen 3 'LS' engine parts and Gen 1 big block parts making aftermarket solutions sparse at the current time. However, in stock forum (from this particular GM application) with a ECU tune and custom intake/exhaust, these engines can easily see 350hp but please note that this is not what the 496 is built for. Its main role is to make extreme torque and low engine RPM's and this it does quite well. With a capacity to halt over 30,000 pounds, its not a unfamiliar site to see the Green Machine loaded with a 28 foot "Goose Neck" trailer that has a Bobcat, a car, large timber, or I/H Beam building materials loaded beyond what a simple Duramax or Powerstroke could tow dependably, smoothly, and quietly. An ‘Auxiliary Transmission cooling package' was designed, fabricated, and installed underneath the rear of the truck bed behind the fuel cell giving the 4L85E a tremendous amount of ATF cooling capacity. The cooler features an electric fan and a custom aluminum shroud across a 22inch aluminum transmission cooler. The Fan is controlled by a custom programed PIC microcontroller that monitors transmission temperature and displays real time information such as current gear and Tow/Hual Mode status. Alternatively, it can be manually turned on by a switch tactfully hidden below the main dashboard.
