Reply to "Rev kit / Valve float"

George PAdmin.

Rev kits are an ultra high rpm device, used with solid lifter cams. I've never seen them used in an application like yours. Which hydraulic roller lifters are you using? How much lift does your cam have? Which valves, springs & retainers did you install?

I ask because the Ford style lifter will just not rev as well as the Crane style lifter. But this is also dependent upon the profiles of the camshaft lobes, the spring and weight of the valve assembly, which is why I asked about the valve & retainer.

The higher you want to rev this stuff, the more critical becomes the camshaft lobe profiles, using the right lifter, light weight parts & adequate spring tension.
