Re: 454. Is 3,000 RPM cruise so bad?
The engine should have no problem living at 3,000 RPM all day long. In the 1970's and 1980's the 3/4 ton pickup came with 4.10 gears and if you had a TH400 3,000 RPM was 60 MPH and if you opted for 4.56 gears 3,300 was 60 MPH! I have owned several of those trucks over the years used primarily for towing. They all went 100,000 miles and over, mainly on the highway, with no issues. Well one issue, a 1979 I had went 300 miles before it had to go back for a new cam (factory recall due to improperly hardened cams) and found two damaged lobes, was fine for the next 120,000 miles!
