Hi guys, new here anyway i have a 87 190 non-turbo my6 wife drives in the summer. i've never had it on the highway before. i took it this weekend on the 401. where should this car rev at 120kms(about 70 mph) this one was at 3100 which seems to me is way high. i've had cummins in dodge since they came out, im very familiar with off road diesels to, just seems to me this car shouldnt rev that high. it is Automatic, anyway thanks for any thoughts you guys have on this
