Big Chief’s shop truck is a 750-horsepower daily driven MONSTER

Justin “Big Chief” Shearer is known for having some of the fastest street cars on the planet. When it comes to daily drivers, he is no slouch there as well. Shearer picked up a 2007.5 Chevy Silverado with a 5.3L, named Wanda, for his daily shop truck and decided that being stock wasn’t going to cut it.

Shearer started off by adding a mid-size camshaft, Stainless Works headers and exhaust and a F1A ProCharger. In their first round of dyno pulls, the fuel system was running efficient enough to make the power he wanted and they ended up only making around 550-horsepower to the wheels. To solve this issue, Shearer contacted the guys over at Aeromotive and picked up two of their Dual Phantom intake pumps. Once installed and back on the dyno, Wanda ended up making 638-horsepower to the wheels on 12-pounds of boost on just blower.Shearer thought why not add a little more power and installed a Plate Kit from Nitrous Outlet.

Now that the fuel issue is resolved, Shearer decided to add a little more power and installed a Plate Kit from Nitrous Outlet. The dyno results with a 100 shot put the ProCharged 5.3L Silverado just north of 750-horsepower to the wheels, which is very impressive, to say the least. For a daily driven shop truck, this thing is an absolute monster and we can’t wait to see it in action.
