What ever happn'd to rod and custom machine small block hemi's?

Last time I saw them was at the Nats in Columbus about two years ago. I think their problem was cost - cost to manufacture and cost to install, crate motors HP and prices probably killed them. For what you would spend on the conversion, you could get a killer crate engine with half the install issues. I've never seen one of their set ups anywhere except in MoPar Collector's Guide.
