whats your thoughts on street stall speeds 727 info inside

I have a 3000 stall in the Duster. I don't drive it every day. But I haven't
had any conserns with street driving. I have driven it on 4 hour drives at
hwy. speeds and town driving. From home to the Car Craft nats, that the
4 hour trip. Drive it all over for local shows with no problems. It runs at
about 2500 on the hwy. 55-60 mph.
No over heating of the trans. Mabey I'm just lucky.
Works great on the street and at the strip. I change gears for that.
3.23's street and 4.10 strip.
Just my 2 cents worth.
