Stan, Run a simulation for two hydraulic flat tappet cams that have the same .050" intake duration. Not in a 350 combo but a 455 combo.
I'm aware they are not rated at the same tappet lift but just for interest.
Lets look at a comparison of the torque curves or "area under a curve".

The ever popular Crower 60919 cam:

304 /316 ( or what ever seat duration they use these days )
231 / 240 @ .050
.470 / .470 lift
112 LSA / 106 ICL

A very popular UltraDyne Pontiac cam years ago:

288 / 296
231 / 239 .@ . 050
.485 / .507 lift
110 LSA / 104 ICL
