So, it’s going to be quite a ways out until I ultimately have to make this decision, but I’m trying to narrow down my choices on a rear-end ratio once I do the E-Rod swap. I know the Ford 9-inch is popular, but I’m leaning toward the 12-bolt. I’ve kind of narrowed it down to 3.08 or 3.31.
To be clear, I’m not aiming to build a drag strip demon or the fastest G-Body wagon out there. I just want a fast, reasonably fuel-efficient cruiser that I can drive around town and maybe the occasional road trip.
I know a 3.73 would really wake it up around town, but I don’t want it to be too frantic on the highway. I typically cruise between 70-80 on the highway, so I want a gear that’ll get me out of the “drone zone” which seems to be between 1,500-2,000 RPM.
Seems either the 3.08 or 3.31 would bring it above 2,000 at between 75-80. This should also be kind of the sweet spot for fuel economy. I would be thrilled to get about 22-23 highway.
Any thoughts, personal experiences, or advice appreciated. Thanks.
