Why are roller cams so $$$?

That’s basically my favorite thing. I’ll do a nice health solid flat tapper cam again. I have one lined up. It’s a beefy lil’bastard. But that’s about the only reason why. It’s also easier to clear pushrod tunnels on some heads. I wasn’t to fond of whipping out the die grinder on the Edelbrock heads and the Hyd. roller cam.
But that’s what ya gotta do sometimes.
