First off, usage.... is your car a daily driver, street strip, or road racer.... depending on use, profiles for cams and intakes will determine the rpm ranges you will need max power and TQ at... For most of the crowd it is street strip and/or daily drive or both so I will focus here since this is in line with what my goals are...
So, unless you are building a full out drag car cams are the biggest bang for adding power and need to be balanced for drivability.... Intakes are limited for the 2v and the best intake in my opinion by far is the PI intake...once you go to a larger intake like the TFS or Victor Jr... you drastically shift the power curve up and
Most people do a stage 1 to stage 3 cam for their 2v mustangs as an example as they don't want to go too big thinking drivability down low will suffer... This can be correct if you go to big a cam with an LSA over 110 and up... When you go with a bigger duration cam this will shift the TQ and HP curve up in the graph and starts impacting low end TQ/HP for drivability.... but how can you get the best of both worlds?
Lower the LSA down .... some theories are that lowering the LSA down effect low end drivability or idle quality... it does to some extent but having a cam match flow for head/intake and lowing the LSA can net great low end Power/TQ without sacrificing top end power... get the best of both worlds and a nice aggressive idle with the choppy cam sound... as long as the cam events are inline with the build, there really isn't any downfalls unless your cam doesn't match our set up..
