Cam Question

Need to tap some of the infinite wisdom on this forum again. A few years back I bought a rebuilt 350 for my truck. The block was a 3970010 4-bolt main originally from a 1980 truck. The guy had built it for his Chevelle, and the engine was basically done with stock pistons, rods, etc, but with an aggressive cam. I've attached the grind card with the specs.

I recently picked up a rebuilt 700R4 to replace the SM465 4-speed that is in the truck. I called the guy who built the trans and asked for his help to select a torque converter. He wanted to know the RPM Range of the cam. Unfortunately the grind card does not specify this. And I haven't (yet) found a site where I can enter the specs and calculate this.

So my first question is - can anyone tell me, based on this cam spec, a 4.10 14-bolt open rear, 32" tires and a 700R4, what stall speed I should select to best match the engine?

My second question is, if I use this truck as a weekend driver, occasionally load up the bed and occasionally tow a trailer with it, will I be better off putting a stock cam back in the engine and using a low-stall converter? The transmission guy was pushing me in that direction. I understand the heat issue with high-stall converters, just wondering if it's something to really worry about.
