273 cam selection on Desktop Dyno

I have a Dyno 2000 program (not even Desktop Dyno) and was messing around today with solid lifter cam specs for my 273. I messed with the stock specs and tried the Isky E-4, and the Schneider #14202. I also tested a couple hydraulics but diddn't like the results.
I was looking for a cam to replace the stocker with maybe a little more kick
without getting too radical. There's only a couple choices of mild flat tappet
cams for small block Mopars with the E-4 being the closest to stock. As usual the stock cam has the most torque especially at 2000 rpm. And as expected the most radical of the three produced the most horsepower but at 6000 rpm.
I guess it depends what you want as to which one you choose. I changed lift,
duration and lobe centers till I found the best combination. I also kept the same specs but changed from solid to solid roller for more gains. I know the program isn't true but if used as a guide it gave me an idea what changes could do. I tried to duplicate the charts as attachments but can't get there. so here's a few specs;

Stock cam: 248/248 .415/.425 108 degree solid flat tappet
105 hp@2000 rpm 276 lb/ft @2000 rpm
288 hp@5500 rpm 323 lb/ft @3500 rpm

Stock cam 248/254 .415/.425 108 degree solid flat tappet
more ex. 104 hp@2000 rpm 274 lb/ft @2000 rpm
duration 298 hp@ 5500 rpm 324 lb/ft @4000 rpm

10 hp gain@5000rpm

change to 248/254 .415/.425 108 degree solid roller
roller 109 hp@2000 rpm 286 lb/ft @2000 rpm
320 hp@5500 rpm 342 lb/ft @ 4000 rpm
22 hp gain @ 5500 rpm
more torque at low and high rpm

It would be much cheaper to install the E-4 and call it good or spend hundreds of dollars for a roller set up to gain 22 hp and more torque.
This is all just for fun. What do you guys think? toolmanmike
