Sizes:: 
360-408 Stroker -  23.5cc/Step dish 64cc 9.7 : 1 (Set of 8)
Chry. 360 block, 360 rod, and 4.000" stroke crank. Step dish design piston enhances combustion efficiency and allows best performance with less timing. Quench pad extra tall for open chamber heads and will require machining for proper head to piston quench distance. Quench pad will require more milling for closed chamber (Edlebrock or Magnum) heads. The goal is usually zero deck with closed chambers. Use Magnum rods or regular 360 rods with small end marrowed to Magnum rod width(1").
