Well, I guess I'm the odd man out. I do have 2.94s in my 1970 Roadrunner and think it is a great gear for my combo and how I use the car. Running on the highway it is doable, and I have no problem with acceleration with a stroked 469 engine. In fact I was able to run a 12.48 in the 1/4 mile with this car. 3.55s are fun around town, but not on the highway with the engine screaming 3400 rpm at 60 mph while Hondas and Prius' climb our backs. It all depends on you set-up and how you intend to use the car.
3400 @ 60 sounds more like 4.30s than 3.55s, how tall are your tires 22 inches?
3.91 are 3000 @ 60mph with n50 tires
I agree with that about 3.91's. I run 4.30's and a 30" tall tire and I run 3200 rpm at 60 mph. But this eng loves it as it sings real nice cruisin along at 3200. Ron

OK, so I was guessing. I don't know the exact engine speed at 60 mph with 3.55s All I know is I've had my share of short gears in these cars, maybe its just old age, or being spoiled by my daily driver loafing along at 2000 rpm at highway speed, but I just don't believe we need to be winding these engines out to get good performance if we have planned our builds. For all out acceleration, I agree nothing beats torque multiplication.

I love them. I have them in all three of my cars. All have factory 15" wheels and 235/70/15 tires. One is MP 360, one is factory E58 360 and one is factory 318-4. They are perfect for me for mixed driving. I had 3.21 in another old police car that I also had a MP 360 and 727 trans and there were annoying after any more than about 15 minutes at highway speed.
Facts are stubborn things.

That was the original gear in my 74 Duster360. I went to 3.55:1 and really didn't notice that much difference, other than higher rpms on the highway . . . stock E58 360, 727 auto with factory stall convertor (approx. 2600rpm), and 235/60/14 tires. . . .
Before taking trip to Carlisle in 1999, change complete rear end out, for one from Gold Duster, with 2.45:1 gear !! YEAH !! I like to drive long distances, and this makes a great package, rpms are about 2600 RPM @ 70 mph, 22mpg all day long !! . . . haven't changed em since !
Gotta look at what you are using your car for, and build it for you !!!
Cheers
Mark

FWIW, 2.94 and lower will not fit an Alum MP housing without a lot of grinding, I think, since I yet to grind on mine.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I've got a 2.94 Suregrip in my little cruiser with no complaints. I plan on running it till I can come up with an affordable overdrive setup. Cruises great on the highway, still chirps the tires around town, but then I've never implied I had a race car...
