Damn good info
Not to be a stick in the mud but the key word is “Could” and this is not always the case since the rate of lift can be quite aggressive without being a roller lift.
There is also a point of having the lift overly aggressive where it no longer shows a benefit. The more aggressive the rate of lift the quicker the valve springs wear out.
For a Hyd roller cam to outstrip a sold lifter, it has to be very aggressive! Even a solid roller would need to be. Even when the roller cam does have a higher and quicker rate of valve lift, it still looses out on the low lift side.
Beware of what your purchasing and why.
