I have the same setup with the 3.42's and 255/60/15's but I have a six speed. At around 65 - 75 in 4th I'm hitting around 3000 - 4000k which is the same as final drive in a TH350. Luckily I can keep upshifting.

i have a 4spd Muncie in my 78, idk the gearing ratio but it SUCKS at highway, at about 75-80mph its an ear groaning 4k rpm or more, i really want to throw in a 6spd or get a better geared 4 or 5 spd.
