Pros: nasty sounding idle, good power at mid-high speeds, works with all stock valvetrain components (if you use Hemi springs); will clear most pistons if the engine doesn't have a lot of milling.
Cons: narrow power band; requires more stall speed than other cams which will run as hard.
I'd run one in an engine I didn't have an investment in, if I already had it; I wouldn't spend money to get one. The cam is dollar-for-dollar the most significant piece which determines how your existing set of parts will run. I wouldn't try to save $50-100 on the cam after buying pistons, machine work, etc.
