Just for comparison. I have a 5.0 stroked to 347. Cam is 236/242 Dur @ 0.050" lift is .555 / .576 with a 110 deg lobe separation installed at 106 intake center line. Advertised 287 / 293 @ 0.006" roller cam.
Engine idle is choppy, but smooths out by 1800 rpm. It does not like to be lugged in 5th gear below 1800, but it can be driven down to 1600 rpm with a bit of care. It does not lack torque at any rpm in the first 4 gears. I believe the .62 5th gear would drive up a 10 deg grade if you keep it above 2000 rpm (never proven).
347/482 * 1800 = 1295, so in theory my cam / head combination would be smoothed out by 1300 rpm with your cid. Now these two engines are too far different for this to be a valid comparison, but it makes a point.
