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.
- Intended use of the car
- Desired power rpm range
- Desired torque rpm range
- Carburetion
- Cylinder head modifications
- Valve spring pressure
- Axle ratio

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
