As you say, I build mild daily drivers. Nothing wrong with your plans , but a 1800 stall is kind of weak. If i was building a performer cam 350, 3.73 rear I would still use a 2800-3000 stall. A 3000 rated converter is only going to footbrake till 2200 at the most. There are so few driving conditions were it will feel loose, or greatly affect mpg. The benefits of a 3000 stall are imediately noticeable from the moment you hit it. If you build a nice street ride you might want to include a more aggressive stall as part of the basic hotrod package.
I used a 4200 stall in a race vehicle . That was a slush box. You could brake to 3000 at least and scream from the hole. A 3000 is totally different.
