your thoughts on a street cam

The cam works with the cars weight, converter, rear gear and tire size.
The duration has an intended rpm range. It should work with your needs and the above.
If your heads are stock, then I would stay under .500 lift.
If your gear ratio is a 3.55 and your tires are 26 inches (235/60/15) or smaller, generally speaking a Hyd. Flat tapper cam of 230*.050 is a good match for a street machine and the above. The converter works with the cam to overcome the missing (very) low end torque. You'll never know its gone.

If your keeping the stock converter, stay under [email protected]. (A [email protected] is excellent) It will work with 3.23 gears & up.

Adding gear makes torque at the wheel. So a lack of engine torque is overcome by adding gear. Also, adding converter.
