Product Description

The RMRE Super Series 583 features 20° Reher-Morrison / Dart heads. Reher-Morrisons answer to big power at an economical price!  Also comes as a 598 Super Series!  The 583 / 598 20° Dart headed engines are designed with Bracket racers in mind. The 20° Dart heads provide maximum power without going to our Raptor style head. Low maintenance with power and torque for throttle stop racing!

NOTE: Tests were performed with NON-OXYGENATED fuel. The use of OXYGENATED fuels (Example: VP113 or Q16) may produce a power increase, but will require a tuning change, including increase in jet size, for optimum performance.
