440Source Solid Roller Lifters

Out of curiosity, I gave 440source a call today. Sounds like these lifters have only been out for a few months, but they've already sold a number of sets. A lot of them sold to drag and drive guys apparently.

The guy I talked to seemed very knowledgeable and mentioned that he plans on running a set on a stroked BB build soon. He said he'd run them with a hydraulic roller cam with tight lash. Not sure I'd use them quite yet, but it's interesting none the less.
