Dart’s 13 degree cylinder head has been the standard in Dirt Late Model racing for years, and MBE has advanced this casting farther than anyone. While other cylinder head porters have stuck with the same designs, MBE’s R&D program has continually found ways to improve its version of this head year after year. In fact, MBE’s 13 degree program has proven to be worth 30 horsepower and 39 lb/ft of torque better than practically anything else on the market. Add to that an intake manifold custom ported by MBE to your engine’s specifications, and you have an unbeatable combination.
