What stall converter for my 408 stroker

Well, converter technology has come LIGHT YEARS ahead of what it once was even 10 years ago. You can have a converter made that will flash to 5,000 RPM but drive around on the street like a stock converter. They don't have the slipping transmission feel anymore. His camshaft will be coming on like Katie bar the door at about 4K. He'll figure it out, I'm sure. I admit you're right though. The strokers do have an incredibly FLAT torque curve, so it would probably work well most anywhere in the curve. If it was mine, I would want the converter to be all over peak torque.
You’re also right about converter technology. I think a lot of dudes like to buy off the shelf for instant gratification and cost. Me too mostly on the cost end of things. If I was ever happy with anyone of my cars and didn’t want to change things up as often as I do I would also likely buck up for a ‘made for me’ converter to suit the exact setup too.

The converter I have now is a billet job (the 2800 one I mentioned earlier) was made to go behind a massive torque 505 big block that I had on hand so I used it. I didn’t know what it was good for and just tried it, luckily it was close enough to my needs but truth be known for my current setup I’d probably like something around 3200rpm, maybe 3300
