Rear gears
#11
Like most people have already stated, it really depends on your setup. If you are running a 3 speed automatic, you are confined to gears of no more than 3.50, 3.55, or 3.73 if you want to cruise at a decent speed down the road. If you are using a 5 or 6 speed, you can afford to go 4.11 or 4.30 without sacrificing cruisability. Also keep in mind that you need to keep the rpms in the power band of the engine while cruising. If you don’t and you are below your power band, the engine will feel like it’s “lugging” while cruising.

Cainsable. I finished up my 4.11 gear install last night and got to drive it around the block a few times, so far I am very impressed with them. The car feels like it lost 300 lbs. and gets up nicely now. When I get more seat time I will post more thoughts on them.

a 3.70 gear might be worth a try-should be relatively obnoxious and loud without being unusable

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

My old 71' Mach 1 had 3:91 track lock with 4 speed.
And a 351C 2V making 400HP camed to max, It was a ripping good time.

I think 4:11's are too much for a driver and 70 mph on the freeway.
Just my opinion.

Made a trip cross country with 3.50, no over drive. Sounded like a nascar race 4 days out 4 back.

I went with the 4.11's on my ride because 95 percent of our driving is below 60 mph and the other 5 percent will be at the 1/8 mile drag strip. I love this setup, the car will chirp the tires shifting into 3rd and feels fast now not just quick like it was before. I was under the impression that the original poster was building a somewhat drag car not a daily driver that is why I threw my experience out there.

Yes you are right I will rarely go over 55 in the area I drive. I am leaning towards the 411

Our local dragstrip is reopening soon so I yanked the 3.50 gears out for a while in favor of the 4.11's. Our stang sees almost no highway miles so this was also a factor for us.

Thanks looking forward to your thoughts
