Camshaft for 5.2 magnum

I am am just a teen but the plan is to put a 5.2 or 5.9 in my 1975 duster and the only teen thing to do is to have a cam that idles good i will admit i am new to the cam thing and i am willing to get a different stall converter and springs just trying to keep it simple and i hope to make about 350hp 400 if i am lucky but that's a stretch.
Excellent, and I agree with @junkyardhero that your goal is easily achievable and in fact I have a perfect recipe for you. 5.9 magnum, comp 264R-14 cam (with spring upgrade), RPM airgap intake and a 3310 Holley 750. This exact combo made 365hp and would be daily drivable. It’s not the choppy LS crowd sound but it has a noticeable idle and works. With a 2800 stall and 3:23 gears in a A body it would rip.
