Nope, they suck IMO. Even with a stock 440 with 27 inch tall tires they got nothing on 3.55s


Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

I've got them in my '68 Dart. If you're looking for fun, don't get them. You want gas mileage, they do a pretty good job. I run a tired 273 behind a 904 and an open 7 1/4. I also run a 205/75/14 tire (26 inches tall). Let's just say I was going up a slight hill one time with my foot pegged on the gas and a late 90's Toyota Corolla passed me up. Besides that, I average high teens when it comes to mpg.

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.

Your problem isn't the gear ratio. A tired 273 makes less power than a late 90's Corolla-period. Hell, my 68 Barracuda with a tired 318 couldn't spin the tires with a 3:91 sure grip. Things are different now and I'm considering a 2.94 for my tunnel rammed 400. The thing made 472 HP @ 5300/ 489 ft/lbs @ 4700 on the dyno and rolled over @ 5400 rpm. No reason to spin it tight, and it's not a drag car anyhow.

I've got 3.23's and 20% OD... about the same as 2.76 with a 1:1 top gear. It works great. It cruises at around 2700@75 MPH. RPM is actually higher than it needs to be for cruising but its nice to have plenty of reserve power without downshift. As posted above, it depends on the combo. This in an E with 496 and moderately big cam (243@.050).

My next built is a 71 Charger 500 with a Nascar theme for the highway and I was thinking of running 2.94s or even 2.76s behind a 440. It's an auto so it is my way of getting and overdrive, I figure the 440 should have enough torque to plus it no to mention it wont be a red light racer. But, yes, it will still need to get out of it's own way for me to be happy with it.


Careful, your character's showing!

3400 @ 60 sounds more like 4.30s than 3.55s, how tall are your tires 22 inches?

2.94's are OEM in my '84 Ram. 318, 2bbl, 833od, and 29" tires.

No probs here, the 3.09 1st grunts it from a stop sign at idle and with the overdrive I'm 1500 rpm out on the highway and getting 20mpg.

Be that much better in one of my old girls and their few hundred horsepower advantage.

"Mister", you're off your meds again.
SHORT gears are higher numerically. ( 3.91, 4.10, etc )
TALLER gears are lower numerically. ( 2.76, 2.94, etc)

All depends on what kind of power you have. We've been 10.60 w/2.76 and 255/60 radials @3700lbs,10.08 w/3.23 and 275/60 radials.

Well MisterBERRI .... no lack-o-meds here ... but yurr "statement" is very-much flawed. And I have heard this before and I put out the "bait"(my capping the word SHORT) and you grabbed-it .....

IF what you say is "true" .... then a fat-tire car is limited to a 7" cheater slick. A big-inch motor is limited to a 225 slant six size. on and on and on .......

The car in my pic has 2.94 gears single leg behind the 440 / 727. A great cruising and around town gear in my mind..
I am 58, been all around low geared cars. My A12 car ( when I was a senior in High school) had 4.10 gears.. What a pain...
Sometimes we read too much hot rod magazine and get STREET mixed up with RACING, I know my friends did when we were younger..
Now with that said, I have been thinking about 3.55 gears with a gearvendor od.. That would make my final ratio around 2.70. but that is $4K away...
Overall the 2.94 gears work great on what I do with my car..

The rear and 727 in mine were removed from a 68 Charger with 2.94 gears. I have 3.23's in mine but the rear tires are 30" tall. If the Charger came factory with a 26" tire the difference in the gearing would be 24 points. (6 points of gear per 1 inch of tire) That would put me at 2.99 final ratio. According to the speedo which still has the correct speedo gear for the 2.94 in the transmission, I'm only off about a mph or so. Great for the highway but with a near bone stock 8-1 383 with a stock converter its a pig from a stop light. Average MPG is about 18 or 19.


Loving all the tears... bawling

Sorry Doc...

We'll try again in 2 years...up

Edited...Looks like it will be 6 years...biggrin

Couldn't agree with you more.

Vipers came with 3.07's and it appears to me that they don't seem to struggle with acceleration.

No reason to spin it tight, and it's not a drag car anyhow.




I will agree with you on that... Big horsepower and a numerically lower gear does sound like a nice combo.
