Quote: I would assome just because they have equal lb specs that they are not equal springs. Surely they are made with different materials based upon what I see in the picture.
Yeah I should of clarified my question. I know the pac spring is a better spring BUT when do you need them other than having a camshaft that requires the psi. Production G3 hemi in the past have had issues with their valve springs and address them but using a bigger spring. In a low budget build I try to save as much money as I can. Like the Jesel rocker system that is 3000.00. I would like to know how much hp there is to gain for the price especially when you are not going past 6500 rpm with a hydraulic lifter?
