Playing around with the ratio calculator. The wide box, dana 20, and 3.07 's put us with a first gear low range of 39.39:1 compared to the 27.01:1 with the t-18,dana 20, and 3.31's that are under it now. If we feel froggy latter we may throw a teralo kit at the dana 20 to up the crawl ratio a good bit. The main goal of this project is to have a cool old school style FS service type rig that is capable on mild stuff yet will run 80 down the interstate and not be screaming. We gotta put some other service items into motion before we start the fun stuff. We gotta take care of the clutch, freeze plugs are shot so we are gonna flush the water jackets when we pop them out, engine was a little gummy looking inside so some seafoam and and an oil change is in order, and the radiator needs some love. Stay tuned!!!!
