[QUOTE="Catmonkey, post: 16589409, member: 124025"] That and the higher 1st gear ratio probably had more to do with lowering the 0-60 times by eliminating the 1-2 shift, but the later cars did have an extra 25 cu. in., so it may have contributed to better mpg. I now have a 13-14 transmission in my car for the 1st gear ratio. I am toying with the notion of putting in 3.90s or 4.10s. My current cams and 3.73s are not that well matched for in-town cruising. But maybe I just need to drop down a gear more frequently. I'd hate to swap them out and not accomplish what I'm hoping. Pretty sure the 3.73s are now too low for any future mile attempts anyway.
