Cams for 318's

Hello,

I would like to replace the original camshaft with this Lunati one in my 318

Lunati 10200701
Lunati 10200701: Voodoo Hydraulic Flat Tappet Camshaft Mopar Small Block 273-360 Lift: .454" /.475" - JEGS

Currently cylinder heads are original (cast iron) with Weiand dual plane with Holley 600 mechanical.

As there are a lot of hills in my city, I'd like not to lose torque at low rpm but gain something at medium RPMs

What do you think? Am I making the wrong choice? Any recommendation with this cam ?

Thank you!!
