Proposed cam specs

Please tell me what you think about this cam.

I contacted a cam grinding company and gave them a description of my car ( 1970 Dart, 360 roller cam, Holley 600, Wieland intake, stock bottom end, stock Torque converter, 2 1/4 dual exhaust w/ turbo's) and its intended use (weekend cruiser with some muscle, street only)

They suggest 224/232 @ .050", 274/282 adv, .519"/.528" lift, 112 sep

I did not get to talk to them, this was done in an email, but I don't know how much different this cam is from the stock one. Any feedback?

Thanks
