Purple Vs Lunati Voodoo

This is my first Mopar its a 1973 Dart Swinger 318 auto, now I normally play with the Blue Oval & they tend to like 500 lift with 280 deg dur at a min.
I have noticed that there is a strong debate over Mopar Purple & Lunati cams & it looks like hydraulic cam for Mopars are under 500 lift.
THIS DART IS ONLY GOING TO BE A STREETER WITH CASUAL DRAG USE & I only want hydraulic.
Here is the specs on the mods that I'm looking at. I have not brought anything so far but I will be going through Summit.

318 auto remeber 1973 has low compression I think its 8.9 to 1
Offenhauser 5700 360 deg single quad high rise
Holley Street avenger 670
Proform extruded shaft mount roller rockers 1.5 ratio
Headman Headers
Carter hi volume mech fuel pump
Standard heads with slight clean up
904 with shift improver & 2800 stally
3.5 to 1 rear LSD
Tyre roll out 26inch
Rev range 1800 to 6000

I'm after a cam, lifters & springs to suit this combo, your oppions & what has worked would help

Cheers
