What gears with OD A-833?

I'm in the L.A. area too, so I know our freeways. If there's no traffic and you're not doing at least 70 to 75, then you're just pissing off everyone behind you.

Seems like cruising at 2 grand at 72 mph is pretty ideal. I wish I could do that, but currently I have a 4.10 gear with a non-OD 4 speed. I would love to have an OD, but I'm looking at changing my rear end to a 8 3/4 with a 3.23 instead. Like you, I currently have a 8 1/4 rear end.

Anyway.... If you like how it drives and how it cruises, then why spend the money? Just stay with what you have. But if you really want more "oomph" then I'd say go no bigger than a 3.73 or 3.91 gear.

Here's a fun gear calculator for you. You can plug every thing in such as tire size, transmission gear ratio's and of course rear end gear ratios. Check it out here: RPM & Speed & Gear Ratio Visual Calculator
