I've seen some LS stuff up around 8000 rpm with hyd rollers. So it can be done but it takes very careful selection of parts.


I too thought this was pretty much the “norm” in the LS world.
We have an aftermarket LS based build going on here......... N/A application with a carb for a dragster.

After numerous calls to shops who predominantly work on the LS platform, they are recommending a solid roller for this build.

My advise for those looking for quiet operation....... don’t go with the type of combo that’s “set on kill”.
Smoother lobes that can operate adequately with more moderate spring loads will generally be quieter, with likely somewhat less power.
