By the way 2ndopp, I think you'll be alot happier taking your 360 to 408 cubes vs. doing a full swap in to a 440. I'm a big block guy but it takes alot of time and money to completely change over, usually you're talking about changing radiator, engine mounts, headers, different tranny case, maybe converter, engine accessories, etc etc.

I will never understand how people calculate gear ratio, especially the auto guys. They gear too tall and force the converter to slip and then say the engine rev's too high. Obviously, I don't care for automatics either.

I can't think of a single use for a 3.54 gear for a muscle car oriented set up. It's not a camry.


Please let all the manufacturer's know which parts you don't approve of so they can stop production immediately! And feel free to make a list of how you want us to build our cars, you crack me up.
Hopefully you'll be cruising around my neighborhood so I can show you how well 3.23 gears work with a stroked big block.
Not to mention the maroon colored Dart here on Moparts that runs 9.50's with a 3.54 gear. I hope he built the rest of his car to your expectations. Are you running less than 318 cubes with your 557 gears? eyes


I don't care what you do. You get butt hurt awful easy.

If you think a 3.55 is a LOW gear I can't help you. Get a life.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Not butt hurt at all, and my life is amazing. Just trying to point out bad info, not everyone needs 557 gears in their street car and street gears aren't just for Camry's. Have a great day! wave

What is the lightest weight two speed rear differential available,
like those in 1980s Mack midliners
or the smallest dump trucks?

In past posts we have discussed the short lived two speed Dana 60 that was available one year on Mercury Cougars.

As far as I know, 2 speed rears are medium duty truck only... like the midliner or an old Dodge D600. Cars and HD trucks get it done with the transmission or transmissions.

Ford offered such in the mid-40's and early 30's across their product line.

So Bonny and Clyde could have had a two speed rear axle on some of the many Ford V8s that they liked to steal?
