Thread: VS Cam Build.

When measuring the above rocker using the shiny part as a contact point the rocker ratio varies from 1.53 to 1.81. Pretty crazy huh?

does that not happen on all pushrod engines........(contact patch on rocker)

edit: a 1.6 rocker with 257 lobe lift, is still a 1.6 rocker at 300 lobe lift

No, roller rockers are a fixed ratio. Stock rockers are not a fixed ratio. The higher the lift, the higher the ratio. (to a certain extent, obviously.)

read #40

now tell me how they are not on a fixed ratio, the wear patch does not mean the ratio varies
