Cam Swap

[jack330]

New here and need experienced racers opinion.
I have a big block Mopar with a giant solid lifter Bullet cam
I am putting in a Lunati hydraulic cam and lifters.
Is it necessary to swap out the existing Bullet springs.
The opinions I am getting are all over the place on this

Thanks for the help

The correct answer is maybe based on the info given. The cam card for each cam will tell you the seat pressures, which will answer the question with a yes or a no.
   The bigger question is why are you going from a solid to a hydraulic? Thats a big step backwards.
