Need cam ideas for my 318 Duster

Yes AJ on the street, your not gonna spend much time at peak hp and or rpm.

Say stall (2500-3500 rpm) to shift points (5500-6500 rpm) say gonna spend a lot of time 3500-4500 rpm say 4000 rpm average. How do you make most possible power around that rpm and or rpm range? Easily more torque and where do decently built street engines make peak torque? It seem generally at those rpms. So how to make even more power around 4000 rpm without going bigger or non NA, build to a higher lbs-ft per cid, hows that done? generally better top end, This idea building to 5500-6000+ rpms doesn't help mid range power is ridiculous, peak torque generally happens 1000-2000 rpms lower say 1500 rpm average than peak hp, so peak torque at 4000 rpms puts peak hp between 5000-6000 rpms and shift points 5500-6500 rpms.

So what about under peak torque an engine generally still makes decent torque 1000-1500+ rpms under peak, and generally way more than a stock 2bbl version of that engine would.

Question how much cam is acceptable to the OP in idle and general driveability?
Performance wise the engine should be fine.

And this 2.02 is too big and too much shrouding is mostly nonsense, that's the minimum most performance heads come with, it is what it is and will be fine.

At street rpms idle to 5000/6500+ rpms, so rpms are somewhat fixed but some room for overlap in potential, so basically around 20 cid is ruffly considered a step up in performance potential starting at 170/198/225 skip a few 273 skip a few 318/340/360/383/400/413/426/440 etc.. 318 ain't at the bottom or top it's in the upper middle.
