rear gearing with a four speed A833.

A definite sign of the times is thinking 3000-3500 RPM cruising speed @60-65 MPH is Way to high! When in fact these were acceptable perimeters back in the 60's - 70's and even into the 80's. Now days with the younger generation use to 5,6,8,9 speed transmissions and every car/truck coming standard with tachs. The thinking is that a car/truck needs to turn 1500-1800 RPM @70 MPH to be "right".
This is why I drive my 07 4x4 CTD when towing or traveling. But when I drive my 500 cu.in Dart to cruise nights, I really don't care about the RPM's @60.
Don't worry RRR, your still on my Christmas card list. LOL

I would also like to point out that in modern times lower RPM is the norm because we no longer rely on technology from the 60's and 70's. vehicles make plenty of power with low RPM. It makes for a longer lasting engine and drivetrain as well. Now when people look at cars with 100,000 miles they feel they have a low mileage car. In the seventies though, low mileage was like 30,000. Why do you think 70's tech engines are wore out after 100'000 miles. As technology advances people find they can have their cake and eat it too. Which means we can have low rpm, be comfortable and still make power. Oh also, check out variable valve timing. What an innovation in technology. Like I said, have your cake and eat it too. That's just an example.
