Wheel to Wheel Powertrain
Based in Madison Heights, Michigan, Wheel to Wheel Powertrain has several claims to LS engine fame, including the first 6-second power-adder drag race engine, and the first 8-second N/A drag race engine. The company focuses heavily on street engines as well, and says, "We have built countless variations of LS family engines for customers over the years. Using all of that experience, we choose what we feel are the best parts to make good power and torque, while maintaining excellent driveability, idle quality, and most importantly, durability."
