340 528. Purple cam question

The more I learn about camshafts, the more I do not like hydraulic. All the Chevy boys run um. LOL

We have this customer.....has a pretty nice pro street 68 Chevelle. Nice lookin car. Let "somebody" build a 540 Chevy fat motor for it. FIVE HUNDRED FORTY KYOOBS of Chevy big block. Put a hydraulic roller in it.

Makes zero sense to me. Maybe even negative sense.
