Solid and Hydraulic lifters on a stocker.

[Dan Fahey]

Talked to John Partridge today at Bullet.
Only advantage to go Solid Lifter if the Engine has to Rev.
For example 7500 rpm or more

Light Weight Solid Lifters are available.
Meaning lower Valve Train Mass.
Which helps Solid Lifter reliability.
Provided adding more Spring Pressure makes them expensive for survival.
