Cam for torque question

If after your tune up and still not satisfied.
I wouldn't go with less cam probably won't gain much downstairs just lose top end.

The reason people say don't build a 318 isn't cause they can't perform. But people are barely willing to gear a 360 properly nevermind a 318. 3:55 gear is what the average guy runs that's why 408 are so popular. To me 3.91 is the minimum 318 gear unless you after an econo combo and with your parts list seems not to be the case.
