What Cam and lifter set for stock 1965 273?

The Dart Charger 273 cam (4 bbl, Hi-Po ) had a lift of .425 I/E, 248º duration, and 46º overlap.

IMHO there are a number of factors in selecting a cam.

If you want to go to a hydraulic cam, you may want to consider the 340 repro cam at Mopar Performance. It's a bit more aggressive than the stock Charger/Commando mechanical cam IIRC the lift is .441
