Big 79 Bronco
I own a 1979 bronco with a 460 out of a 71 Lincoln. It has an oversized cam and a 750 edlebrock carb. It has a 7 inch lift with 38.5 inch tires, dana 44 up front and ford 9 inch in the rear i believe. It has a C6 auto trans and i believe 4:10 gears in the axles. Right now the gas mileage sucks in the city but not to bad for what it is. It has 51k on the engine and 7k on the trans. I got it on the highway and at 70 miles i was reving at 3000 rpm and the tires were loud. Sounded like an airplane was behind me. Now i need to travel 4 hours from raleigh to Charleston atleast once a month. How it is now the gas will be expensive and the ride will be loud. Now if i put 33 inch alterains on the bronco how much would that affect my gas mileage and would i be able to go faster because im not lugging around the 38.5s. Would it rev higher. Or would it be better to just buy a travel car. Thanks for any input.

only one way to go, BUY A TRAVEL CAR!!! if you go smaller on the tires, you final drive ratio will fall way down low. at 70 m p h with 33s you would probably be revving around 3800-4000, not good. buy a mustang or something for gas mleage, keep the bronco for fun!

I drove my 79 Bronco from Chicago to Atlanta on 40" 6 ply Denman Ground Hawgs with a combination 10" custom lift. IT WAS BRUTAL!!!!DON"T DO IT!!!! I got 7 miles per gallon down hill with the wind at my back. I don't think it would get much better going over a cliff. It's a lot of fun, just not on a long trip at highway speeds.
