I'm looking to build a 13mm pump for a project truck, does anyone know the bosch part number for the desireable 13mm p&bs? i do have many 13mm kamatsu p&bs but not sure how the torque curve and timing adavance of the helix would compare to the bosch ones that most guys run in there trucks. The kamatsu pumps that these come out of run a much lower rpm than the standard dodge p-pump
