highway cruising with 4.10 gears

I just installed those mufflers on my Magnum. Glad to read what you wrote. The car has 3.55's on 26 inch tires.
I do like the 3.21-3.23 for Hwy. driving. The 3.55's are also OK.
My beast with 4.10's doesn't see extended Hwy. runs. (Over two hours)
That could be annoying! LMAO! The car is also designed for stop light stompings. So I can live with it since it doesn't go far. The two hour run to the track is seldom and easy to live with.

Isn't there a thread on that tran's swap here?
