Cams Away!

New lifters on a used cam is totally and 100% acceptable. You simply just break them in like a brand new set. Soon as it busts off 2500-4000 for fifteen minutes. Done.

That said, if it was me and I "just wanted" a new one, I would seriously consider this.

DODGE COMP Cams 20-671-4 COMP Cams Nostalgia Plus Camshafts | Summit Racing

The Comp Nostalgia line is ground to simulate the old purple shafts, but with modern and MOPAR SPECIFIC lobes. This means this line of cams all take full advantage of Chrysler's larger .903 lifter diameter. That's a damn good grind and will probably be about right on top of what you had. Notice they gave it a split duration. Kinda brings the purple cams into the 21st century.
