Cam for stock 318

You need to clarify "wake the motor up".
A bigger cam and kit,will wake it up at higher rpm, all right.But without a corresponding compression bump, it will make off-the-line performance sleepier.Then you will be buying gears and possibly/probably, a higher stall TC.
So the place to start is with a cylinder pressure test.
And then maybe gears, depending on intended useage, since you'll likely be going there sooner or later.

If your cylinder pressure is 120 or lower, I sure wouldn't cam it.
Between 120 and 140, you will have to be real careful with the ICA. From 140 to 160, you can be more bold, perhaps something up to 220* tops. At 165, maybe enough for the 268er, that everybody loves. At 185, there's quite a bit of room.
But don't get excited, most teeners fall below 130. Occasionally they creep up a bit. Mostly, well used, they come in at less than 120 honest psi.

And something else to consider is weight.Most cars can loose 100lbs pretty quick. Some can lose another 100, but it's tougher. 200 lbs is worth an easy cam change, probably more at your power level. And you will really feel the increase in off-the-line performance. My back seat was 70 lbs. No one ever sat there. It was the first thing to go. I've never missed it.I don't even know where it is anymore! Oops sorry;the spare tire was the first to go.Steel wheels;gone. A half a tank of gas is about 40 lbs. A/C not. I kept the P/S and booster tho.
You can't believe how much the rear window in a FB barracuda weighs! But it has to stay.
