Message: [QUOTE="Big Bore, post: 50960, member: 760"] Going back and looking at the final drive ratios, a ZF6 with 3:55's has way better final drive ratios in the first 4 gears than a ZF5 with 4:10's, with final drive ratio in OD WAY TALLER . Which means it will get a heavy load started better, faster and easier, while still being able to maintain lower rpm's on the hiway. I'd say that's a little more than significant. I've been mulling over the idea of an older Ford with a 1st gen 12v/ZF6/3.55's, and the more I think on it, the more I realize that would be the perfect low maintenance high mileage setup. The 6speed would help keep the narrow power band of the 12v in the sweet spot, while capitalizing on it's natural tendency to get good mileage. [/QUOTE]
