It just eats fuel. I can't wait to get my on606 swap done. 6 speed with . 83 od on a 2.82 rear will give a 2.34 final drive. That will be so nice .

Mine is a ‘83 300SD. Mine will cruise at 80mph all day as well, heck it will cruise at whatever speed I make it, I simply just do not like the high RPMS. At 70mphI am running 3-3100rpms. It’s plenty loud and I just park it there. I have driven faster and I know it can do it no problem. However for me personally I just draw the line at 70mph which is 5mph faster than most our posted speed limits here in Cali anyway.
