I'm getting close to switching to a roller cam in the big block!

She's ugly out there. So what lifters are you looking at ($$). Pushrods probably 3-400( smithbros) , cam button and shims fairly cheap

Dwayne likes the Comp Cams Evolution lifters. They have a hydraulic cylinder that is replaceable if it fails. I was told that this cylinder is an OEM part for some late model applications which means that it would comply with reliability demands and noise concerns.
The main reason that I chose a hydraulic cam was to reduce noise. I've ran solid lifter cams for over 10 years and it would be nice to reduce some of that clatter.

a tight lash solid lifter cam vs a roller. the only plus for a roller is the lifters can't go flat. I can't see any other advantages for a roller cam but a lot of disadvantages that are mentioned here already go back and look at the posts. I will add one more the roller has a slower ramp off the seat for less performance. A hyd roller will also lose lift at high rpms. a perfect spec out solid and a perfect roller you will see very little or no power gain.
