A friend's engine is getting rebuilt. Stock replacement pistons, Colt Cams Stage 3 cam, 100 hp injectors, Air Dog 150, ATS T3 manifold. Truck will be used for towing a trailer and occasional sled pull. Truck just had a Southbend dual disc street clutch installed. I'm thinking something in a 62mm. Anything out there that isn't a custom built turbo?
