Most likely, you have an 'Hydraulic' Camshaft in the 318 now.
* Do you plan on having a Valve Job performed on the Cylinder Heads ?
* Or, do you just want to swap out the Camshaft ?
Seeing what you have and want.
You should look for a Camshaft with the following profile >
Lift ................................ .430" to .455"
Advertised Duration .......... 260* to 270*
Duration @ .050" Lift ........ 210* to 220*
LSA {Lobe Separation} ..... 112*
Lots of 'Bumpsticks' in that range to choose from.
