Solid Roller Lifters on Hydraulic Roller Cam

I've never had an issue using oil through lifters and push rods either. Just about every engine I build has them.

As far as the cam issue, you need to talk to a cam grinder, this is not the place to get advice on a subject like that. None of these guys design cams.

Yeah, don’t listen to guys who have done it and are still doing it.

Hey, do you know where Comp got most of its tight lash street roller lobes from? Of course you don’t but lucky for you I’m going to educate you.

Comp took most of its hydraulic roller lobes, printed a tight lash number on the cam card and it’s like they reinvented the wheel.

A three year old syphilitic donkey could learn that with a Comp master lobe catalog.
