Another cam question

[jackedup]

So I finally got my first ride and now I've got to get her runnin right. Not sure what my engine specs are, all I can tell you is that it's a 2 owner 100% stock 71 c10 lwb with a 350 with 4 barrel carb, automatic trans and dual exhaust. Stock heads, intake, etc. I have found the reason it runs rough and is sluggish is due to flat spots in the cam. I'm looking at this as a opportunity to upgrade the cam with one that has improved low and midrange torque without killing it on the highway as it will be driven regularly. Wanting a cam that "matches" everything else stock on my engine. I'm interested in this cam generically referred to as a "RV" cam. Been looking at the edelbrock performer plus and the summit racing sum -1102. Any suggestions or words of wisdom are appreciated.
