Camshaft for 5.2 magnum

TT5.9mag said
There are plenty of aftermarket roller cams for magnum engines that drop right in. And you can reuse the factory roller lifters, dog bones, spider, and pushrods. The stock magnum springs are weak and with any cam upgrade, you need springs. Why don’t you tell us what you have and what you want to do with it as any recommendations without that info is a shot in the dark at best.

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.
