308 head & XR280HR-10 Combo

I started building a new 360 and installed an XR280HR-10 camshaft.
230/236 at .050 and .541/.537 110° Sep.
The engine is a 1989 roller motor zero decked @ 9.8:1 with 308 heads that have had 2.02-1.60's installed. I 'm planning to use a an RPM Air-Gap. '69 Dart/ Auto 904/ 3.55 SG.

After the Under-whelming results that Desktop Dyno spit out, I'm beginning to have second thoughts on the cam. It's gonna be a driver but not daily, mostly weekend and cruise-in useage.
I was hoping to get some opinions on this combo and/or some input on this cam from anyone who might have had or has the cam.

How does it sound, any lope?
Any power output estimates?
How is this thing gonna pull?
General opinions on how this setup could be improved.
Thanks in advance..
