To the average, every day enthusiast, the idea of building a 305-cube small-block might seem like an outdated premise, or a “waste of time,” but to those with close ties to the circle track community, the idea is very alive and very relevant today. With the right combination, those 5-liter throwbacks can absolutely sing, and provide the right balance of horsepower, torque, and revs that circle track racers require to be successful.
MAHLE Motorsports is based out of North Carolina, smack-dab in the middle of circle track and NASCAR country. For them, the need is impossible to ignore, and that’s why they’ve added their 305 pistons in PowerPak form. Check out all of the details below!
