so I lost the lb7 this past weekend, loud knock and white smoke, I have a 2004 crew cab 4x4 DRW I use to pull trailers around 20,000lbs my choice is to buy a rebuilt long block or build something to handle pulling trailers. I have afe intake, edge programmer, billet torque convertor what would a solid good towing build be? also I have stock clutches in tranny
