Re: Carburetor
I agree with Geezer "You’re basically driving a big barn door down the road".
It's easy to forget all the incremental changes that have been made over the years to increase mileage.
Things than are gone;
90W in the transmission or differentials.
Non-lock up transmissions
External radio antennas
Flat grills
Exposed undersides
Air conditioners that require 3lbs of refrigerant
Steel pumps of any kind, p/s, transmission or air conditioners
Huge rear-view mirrors
Three speed transmissions
The new directed injected motors are more efficient than any SBC every thought of being. Add displacement on demand and light weight components and you have a truck very different than the fifty year old trucks we drive. Did I forget to mention the new oils?
Yes, a good tune will help. But fewer and fewer are daily driven. However, I did see one at the gas pump today. I filled up my Silverado to the tune of $114. He must have to four gallons of fuel into his 1969 or 70 Chevy truck he was driving as it only took a minute to fill.
Many of us drive our "toy trucks" and don't care about the fuel price as they don't go much further than the next care show.
Give it your best and hopefully you can get mileage into the teens. Driving like you have a Farmers Insurance tattle-tale installed in the vehicle.
Or drive it like a rented mule and have fun.
Whichever you can afford or enjoy.
Cheers
