t’s clear that Art Morrison Enterprises (AME) understands the truck enthusiast’s mentality of “bigger is better” and threw out the rule book when engineering their new C10 chassis with its beefier suspension control arms, bushings, crossmembers, and framerail design. Check the box next to the “independent rear suspension” upgrade and you have the ultimate foundation for the sport truck of your dreams. One lucky truck body will be sitting on top of the chassis you see before you, especially now that the team at MetalWorks has layered on the best performance products in the industry. The end result will provide the makings for the ultimate C10 truck.

In part 1 (Oct. ’22 issue of CTP ). of the AME C10 chassis feature assembled by MetalWorks in Eugene, Oregon, we showed how the professionals prep the chassis for coating and assembly of the suspension components. So, what’s left before adding your truck’s cab and bed to this performance chassis? Here we’ll cover how the MetalWorks team completes their final assembly of the rolling chassis package that features a supercharged LT5 GM Connect & Cruise powerplant. Additional components include a Wegner Automotive engine accessory drive kit, Inland Empire driveshaft, Rick’s Tanks’ fuel tank, Wilwood brakes, E-Stopp electronic e-brake system, and Forgeline Dropkick wheels.

When your chassis looks this good, it’s hard to cover it up with sheetmetal, but we are also itching to see the truck build finished and how this chassis package performs!

Applying Loctile to break kit
1. Use Loctite when assembling Wilwood brake kits.
Torquing fasteners
2. Torque all fasteners to Wilwood’s recommended specifications.
Installing safety wire
3. After Loctite and torquing fasteners for the rotor and hat assembly, safety wire is installed to ensure the fasteners do not loosen.
Twisting safety wires with pliers
4. Use safety wire pliers to twist safety wire.
Cutting and tucking excess wire
5. After safety wire is twisted, cut excess wire and tuck to ensure the loose end does not rub or interfere with other components.
14-inch brake kits
6. Wilwood 14-inch brake kits ready to be assembled on the chassis. 
Installing rear break rotor
7. Install rear brake rotor. 
Adjusting parking break

14. Installing the LT5 with 10L90 powertrain
AME chassis with an LT dry sump engine
15. AME chassis are designed to fit LS and LT engines with an aftermarket oil pan, such as a Holley pan. The engine used in the chassis is an LT dry sump. In this case the factory dry-sump pan fits the chassis properly.
