The Avalanche you see here is almost nothing like the factory model. Where the stock LS put out 285 horsepower and 310 pound-feet of torque, Bill Creech’s truck now makes 325 horsepower and 350 pound-feet of torque and delivers that torque at 2200RPM instead of the original 4600RPM. The aftermarket 4L60E transmission is chock full of severe-duty components, paired to an upgraded torque converter, and cooled by a 30,000-pound trans-cooler. It stops its mass with an oversized Z36 severe-duty brake kit from Power Stop and rolls on 35-12.50/17 General Grabber X3s. It has a welder for emergencies, tools and spares for every eventuality, and a list of upgrades so long it might be easier to tell you what’s still stock. In other words, we have a lot to cover, so let’s get to it.
