What cam to use in 340

I am currently planning my 340 build for 73 Duster. I will run a 727 (uncertain on converter)3.91 rear and intended fun street use. The 340 is a cast crank and will be bored .020" and a set of 2.02 J heads. I am estimating about 9.75 CR(using the summit calculator) If I don't sell my Eddy headed 318, I might use the heads on that motor. Either way, I will use an RPM intake and 750 holley and headers.
I have several cams to chose from already on the shelf and 2 I would think about buying.
I have a Comp 268 Xtreme 224/230*-.477/.480" 110cl
Erson highflow IH 228/228*-.472/.472 108cl
Erson TQ40 220/228*-.472/.472 110cl
These I don't have, but would buy. Comp nostalga cam 233/240- .474/.474" 110cl and
the famous Crane Cams powermax 222/234*-.467/.494 114cl
I will also be using 1.6 roller rockers, HEI ignition and 2-1/2" duals.
My main choices are the Crane and Comp Xtreme.
Of the ones I listed, what would you run and why?
Thanks folks!
