440+6 cuda specifications

[Mr. 440SixPack]

Well I am looking for 1970 'cuda 440+6 4 speed specifications...0-60 mph, 0-100 mph, 1/4 mile, skidpad, slalom, braking, mpg and things like that.

I have found a lot of different numbers and tests over the years...But I would like to know what you know
Well I will be also happy with specifications for challenger 440+6 and automatic 440+6 cudas. If you have any of these cars at home...Would you do me a favor and take it to 60 and 100 mph and tell me the time you needed. Maybe you have some tests from old magazines and so on...

Just a few numbers I have:

0-30 mph = 2.9 s
0-45 mph = 4.0 s
0-60 mph = 5.9 s
0-75 mph = 8.7
40-60 mph = 2.8 s
50-70 mph = 3.1 s
0-100 mph = 14.4 s
1/4 mile = 14.4 s
Braking from 60 mph to 0 = 128.5 ft. (d**n! thats very good )
Fuel consumption = 9 mpg

I have never found any handling stuff except braking.

Thanks for your answers and time.

Interesting stats!

Here's a road test from SPORTS CAR GRAPHIC magazine, November 1969, for the 440-4bbl Challenger. I'll look in my old magazines to see if there's any for the 6 bbl version. I hope this helps in some way.

[DAYTONA]

...the only one I can verify is the 9 MPG..

...interesting info

[Robert1050]

My 'ole 440-6 Cuda used to do about 6 - 7 mpg on the street & a wopping 8 - 9 on the highway.  It had 4:10s so I wasn't expecting much more, besides I had a lead foot & the citations to prove it....

[chevyconvert]

that car sure leans more than mine does. it doesn't list a rear bar either...

[Bondavi]

Curious....would a 3.54 geared 4-speed shaker car beat a 4.10 automatic bulge hooded car? I understand fresh air induction adds ~15hp.

Does the 3.54 pull harder in the higher mph ranges where the sweet spot of the motor is at, whereas the 4.10 is stronger off line?

Maybe on the quater mile track the 3.54 4 speed might won because of its better top end and extra 15 hp...But the 4.10 has quick launch, automatic shifts faster and 15 hp don't actually help a lot. We just have to try it but I would bet on 4.10 automatic.

Thank you guys for your answers ...BGfish I already have that test but thanks anyway . The normal 440 version was a lot slower than a six-pack car for about a second right? The six carbs could easily compete with hemi while the 4 barrel 440 can't keep up with its big brother. The challenger is also heavier than a cuda so cuda is faster. right? .

I don't know but for me 14.4 seconds on the 1/4 mile it is slow. The AAR can do that. The big 7.2 litre engine with 390Hp in a car with 3720 pounds and 3.54 final drive ratio should perform better. What do you think? Dodge SuperBee six-pack does it in 13.8 seconds and it is much heavier than a cuda...

Here is a full test...


And a proof that six pack could keep up with hemi...

I hope you understand everything Have a nice day

You have to take these old stats with a grain of salt ... those tires were so poor at harnessing even the small block horsepower that it was a joke to go 0 - anything in a big block.  Back in the day, we raced from a 20 - 30 mph roll.  I may get a chance to take mine out today.  If so, I'll do a 60 - 100 run for you which will give you a ballpark number.  I sacrifice a measure of performance at my 2000+ ft elevation, but again, it'll be close.

[sleepychallenger]

Does anyone have the stats for the 383 HP?

[Mr. 440SixPack]

@1970hemicuda I would appreciate that

@sleepychallenger I have these stats on my computer. They are for 1970 'cuda 383, don't know the final ratio and transmission.

0-60 mph = 6.9 s 
1/4 mile = 15.1 @ 93 mph 
Top speed = 120 mph

I was never interested into 383 so I haven't got any tests of it. I only know that 340 can smoke 383 off the line but 383 has better top speed thats it

that cant be right, i have had mine up at 150 mph, and never thought that it was that slow. that makes me very sad.

I am also sure they aren't right but again OLD tests Like 1970hemicuda said...
So you have a stock 383 challenger?  What final ratio?

[Robb]

383 doing 150 mph.... 

assuming 1:1 ratio tranny top gear....   

assuming a 275 / 60 tire.... (reasonably tall, popular size tire too)    youd have to be revved up to 5800rpm and have a gear set around 3.23 or numerically lower

so it seems plausible

Yes, it could happen, but I have to ask if your speedo is accurate too? Any change in tire size will mess that up.
