With any cam, remember that stock valve springs will break with just .48 lift, they are weak

Cheap upgrade LS springs and gt retainers to give proper install height, and holds moderate lift cams well.

A cam shaft opens and closes the intake and exhaust valves simply put. When you increase the duration or lift of a valve opening you lose idle quality and emissions quality in exchange for performance. But this is only the tip of the iceberg. Combustion chamber and intake runner shapes can multiply the advantages of an increase in cam shaft profile.

It's a great investment! But like Dave said, depending on the cam you get you'll need better springs and rocker arms to support the lift. Then a tuner is necessary to keep your 6er running smooth, you can get a 15-25hp gain from the cam and tuner combo.

Is it simple to do? Could I do it myself?

If you've never done it before I wouldn't do it yourself. See if you can find a buddy that's done it before so he can guide you along the way. A shop would probably charge an arm and a leg to do the install for you

Hmm yeah I'm sure I have a friend that's done it before.
Thanks for all the info!

It's not really that hard to do, once you get proper pushrods length it's straightforward assembly like a stock motor, and stock rockers are ok with a .500 lift cam for sure, some use them for more but not sure of the failing point on them

But grab a Haynes manual read up a couple times on all the necessary parts to do for swap, you can do it just take your time, I had help the first time second time I did it on my own, was pretty easy
