I am so confused. Please help.

I have the following: 72 C20 350/350 and QuadraJet Carb. I have a 14 bolt rear. 3 speed automatic.

On the freeway I am getting 3000 RPM's at 65mph. So my gas goes very quickly.

I called 4WheelsParts in Redondo Beach Ca. and asked if I could change the gearing to get better mileage. I suggested 3.08. He said no that would make you soooo slow off the line. I have done many searches here for other peoples mileage reports and setups and they have many of the same things I do except for the gearing and get better mileage. The motorand trans and carb are all new as far as mileage goes but not as far as time goes. It sat for a while during the rebuild.

How do I get my RPM's down for freeway driving and still not lose performance? I guess I have 4.11 gearing and he said that is good and to keep with that.

BTW I have 16" 265/70 R16 tires that are old and hard. Do I need to go up or down in tire size and rim size? I am getting new tires and wheels this weekend.

Please help. The mileage is killing me. **I know not to expect Toyota Prius MPG's.

Although it is kinda the polar opposites when you are next to one. One gets 50mpg and one gets 8mpg----Wonder which is which

Anyway thank you for your help, It is greatly appreciated.
