Go for it, Find that elusive 4:11 Eaton HO72 gear set from a 67-72 Chevy 3/4 ton truck with an automatic transmission. When you have that, unbolt the rear axles from your truck, and pull them out a few inches. then unbolt the 5.14 gear set from your truck and remove it. Then lift your 4.11 gear set up and install it into your rear axle housing, reinstall the axles, add gear grease and go for a drive, now able to keep up on the highway.
The real challenge is to find that 4.11 gear set as a lot of them were snatched up by the circle track dirt racers thru the years and also a bunch succumbed to the price of scrap. You wont find that gear set cruising down the interstate but get out and beat the bushes in rural areas and you will find them.
