The LB7 Duramax motor under the hood was the first stepping stone in this build, as major horsepower would be needed if Moon wanted to begin chasing down the 12V Cumminses at the pulling track. The motor was pulled and built from the ground up by Moon. The crew at Gillett Diesel Service (GDS) modified the pistons and cut a custom keyway in the crank before assembling the block with Crower billet connecting rods. ARP main and head studs were used to hold everything together. The injector studs, billet injector hold downs, hi-rev spring kit and cam all came from SoCal Diesel. Any good motor build starts with proper machine work, so the guys at Randy's Engine and Machine were called upon for their expertise. Randy's did all the block work, including porting and assembling the heads and even balanced the entire rotating assembly once the long list of aftermarket parts was put together.
Once the short block was assembled, Dynomite Diesel injectors were installed, fed by PPE's dual fueler CP3 kit. A BD Power high flow exhaust manifold was bolted on to replace the restricted factory unit as well. GDS has been in the turbo building market for a long time, so Moon knew they could come up with the perfect charger for ultimate airflow while still complying with local 2.8-inch inducer pulling class rules. A Garrett GT4202R was built in-house to meet the strict 2.8 compressor rules, without hindering performance.
With the motor modifications done it was placed back in the truck and a Magnaflow 4-inch exhaust into a 6-inch single stack was mounted up to expel gasses from the large lung that now found itself sitting atop the motor. A Fass 200 gph fuel system is used to supply fuel for the PPE dual CP3 kit at DDP injectors. Tuning is supplied through EFI Live software that Moon continues to improve as more time is spent behind the wheel. An Edge Juice with Attitude monitor is installed in the truck as well, offering great performance adjustability.
