Cam re-grind

I just got to the point of deciding to replace the cam in my 360. I'm looking for the recommendation of some of the gear head guys that know this stuff way better than me...

Here is what I DO have:

1970 Dart Swinger
LA 360
Roller cam
Weiand Action Plus
HP manifolds
2 1/2 dual exhaust
3.23 gears
PTC 2,500 stall converter

Currently the car has 14" rims, but I'm going with 15" and not too tall of tires, TBD

Oregon Cam Grinding suggests:

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

I have no reason to doubt what they recommended, but I'm not too sure of what it is exactly that they spec'd out. Those numbers above ^ mean absolutely nothing to me.

Can I get some input here? I'm looking for some performance here, but this car is being built strictly for the street.

Thanks guys!

Looks ,like a good choice. I have something similar from Howards (110 lobe centers/229/ 233 @ .050"/.515'-.520" lift), on a LA blank in a Magnum 360. with proper tuning (18 initial/34 total @3000) real mellow at a 850 rpm idle.
