512 cu Camshaft thinking

Planning to call camshaft companies on monday for a solid roller recommendation.

400 stroker to 512
10.5 compression
Indy ez-1 heads box stock with some minor cleanup.
Indy max wedge single plane intake
Going into 67 dart approx 3300 lbs
T56 magnum with .5 overdrive
Dana 60 and 4.10 sg
28" tire

This will be 95% street as i dont get much free time. Want a good cruiser.
I have a 340 stroker 4sp now but always wanted more low end grunt.

I was looking at comps 23-703-9
254/260 @ 50
582/588 lift.

Or trick flow 243/247 @ 50
600 lift


I realize cams are hard to find right now
Am in the the ballpark? Or what have others used?
