Its just a finger, its over head cam. How could you make it hydraulic? How the hell do you adjust it?

Bro it doesnt wear faster cuz its a solid valve train... usually solids will be in an engine with a lot more valve lift that spins a LOT more rpm, like 10k and have steeper ramp angles on the cam lobes to really slap the valve open. If you ran solid valve train on an equal cam grind as the hyd the solid would not wear any faster...

I wouldnt build an engine with out roller valve train and id probably go with the solid stuff so i could rev it harder.... solid roller lifers are less coin too

Even tho the lifter rides against the cam there is an oil port that supplies the lifter to give it the hyd effect,

Id rather run the solids in that too,

almost all dohc motorcycles are solid shim under or over bucket and go thousands of mile between valve adjustments...

When you float your hydraulic valve train is when bad chit starts to happen in a hurry...

Its not you moms grocery getter its an 1100 hp beast...

I had a 302 sbc i spun 10k rpm with .690 lift solid roller, the cam lobe opening ramp was so steep it was insane. It slapped the intake valve open so violently, that when you put a rag o er the 3.5 header muffler opening at idle you could hear the ping of the sound wave the engine generated in the header and flowmaster copy mufflers i made... it sounded like a two stroke sound wave...lol

Well completed the QV4c 1100 lash. 44 hours all were within spec. Job isn't horrible but takes better part of a day.
