Lunati Voodoo cam p/n 60303 or p/n 60304 with Rhoads lifters p/n 2018. hyd flat tappet.
just my 2 cents
60303
•Advertised Duration (Int/Exh): 268/276
•Duration @ .050 (Int/Exh): 226/234
•Gross Valve Lift (Int/Exh): .494/.513
•LSA/ICL: 110/106
•Valve Lash (Int/Exh): Hyd/Hyd
•RPM Range: 1800-6200
60304
•Advertised Duration (Int/Exh): 276/284
•Duration @ .050 (Int/Exh): 234/242
•Gross Valve Lift (Int/Exh): .513/.533
•LSA/ICL: 110/106
•Valve Lash (Int/Exh): Hyd/Hyd
•RPM Range: 2200-6400
Orginal Rhoads Lifters reduce lift and duration at idle by approximately .010" to .020". Duration is reduced by approximately 10 to 15 degrees. Total lift and duration are restored at approximately 3500 rpm. Typical vacuum increases range between 1 to 3 inches.

Is that a XS282S? I had one of those..I thought it was 242/252@.050 and around .540 lift? 
The .557 is a MP piece, I ran the XE284H & the comp .282 solid in my 451 lowdeck, the heads were mild ported 906s & pulled off 10.8 @ 123 at 3200 race weight with a sucky 1.63 60ft in the heat. This was with the .282 solid & a TR & 2 600 1850s, I ran a best of 10.91 on a 1.51 60ft. with the XE284H & MI single & 750dp in mine shaft air. I had the solid ground custom from comp, we settled on making it a 529/543 on a 108, Dur. @50 was .250/.256, That .282 over the counter is 520/540.
I've heard the .557 is a good cam also, you can go with a custom grind.

I'd use the 528 if this is more of a street car,but if it's a 50/50 street and strip ride use the 557.

Depending on your goals, the one you have sounds pretty good. What gains are you looking for?

Thats a very mild cam. Do you want to run a roller or flat tappet.
Want to stick with the solid; I like lashing the valves.

Faster ET's.
It pulls like a demon to about 500 and then is a little underwhelming to 6200 where I usually shift.
I guess i figured that I might as well use the lift and flow the Eddys have.
As long as I can drive it to the track is all I am concerned about streetwise.
It feels like there is more in the combo up top, but it is, by seat feel, weak up top.
40 squirters, pink brown cam, 81 jets.
If your looking for more ET i'd go with a larger cam & more stall. BB mopars "love" big cams, don't skimp in that area, they like to breath, especially with better then stock heads.

I think the cam you have is about right for your 11 inch TC. Now if you were going with more converter, you could step it up some.
I've talked to Dynamic and am looking at their 9.5" 3500 stall.
This will happen with a minor scuff of the head to get 11:1.
