Hydraulic roller lifters vs solid

I expected more. And how does one cam work with both?

There are lobes that work both ways. I've run solid flat tappet lifters on flat tappet hydraulic lobes for 40 years on occasion.

it's still kind of surpising, that's a large jump

were the hydraulic roller lifters the same brand as the solid roller lifters?

Pulled out Crane lifters and went with Comp lifters.
