While pricing a new cam - the DC engine book says I need these springs.

Joe, I ran the 484/284 hyd. cam with stock rockers arms and Comp springs/steel retainers in a very close set-up to yours. It would run lo 13's at 108. Bob
abdywgn- Thanks for the input. I want to go further away from the hydraulics as Float is a possibility over 5,500rpm. I'm looking to shift now in the 6,500 range to take advantage of the 3.91 rear. I will also need it on the highway with the street tires (off track driving)
