RE: hydraulic roller cams in 428 |

Are you missing something obvious? Yes and no. The heavier lifters need strong springs. But the springs necessary to reach high RPMs cause the lifters to collapse before you get to those RPMS.
So what is needed is a rev kit that pushes on the lifter body and NOT the hydraulic plunger. But no one makes this.
So you can't get there from here.
And all of this just came to me as I wanted to use one. I have been trying figure out why people have reported hydraulic lifter problems with these cams and why they fail to rev very high. These cams do make great power but I have not heard ot any that rev over 5500. (And few that get much over 5000.)
