only problem is if you install the 4.3 or possibly make a 4.1 work you are going down to an 8.75 ring gear from the stock 9 5/8 ring gear. stock tires are 36 inches tall and a 8.75 ring and pinion is just too wimpy for the job. They tried running them in the early WC 3/4 tons in WW2 and they broke like twigs so they upgraded less than 6 months into production to the 9 5/8. with 4.89s in the 9 5/8 and an over drive you could go 90 with a V8. I have never seen the appeal of trying to go an taller. just doesn't pencil out and the lower the gears the better the trail performance.
