Product Description


This Super Series 565 has Reher-Morrison prepped and angle-milled 23° Dart 355 Pro 1 CNC Aluminum heads, bronze lifter bore sleeves, and fully CNCed countoured piston domes. With all these features, the 23° 565 brings incredible performance (1,000 Hp & 800 Tq), consistency, and quality to the track making it a great value for serious bracket racers.

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.
