0-60 in 4 seconds - 04/06/13 11:03 PM
Is 0-60 in 4 seconds or low 4 seconds possible with a warmed up 73 charger 400 engine?

Highly unlikely. It would take traction, gears, and power, more power than a "warmed up" 73 400

What do you think could be a realistic 0-60 time for a car like that?

Right around 6 seconds would be doing pretty good for what it is. Some combos of that description would have trouble breaking 7 seconds. Low 4s is unbelievably quick!!! Others would know better than I but I bet low 4 would equate to about 1.7 60-foot

Those 2.76's are hurting the most. If you want it quicker off the line, use 3.91 or 4.10's.
But it won't be nice to drive on the highway anymore, unless you add an overdrive.

I knew the 4s were pushing it. I would have thought the 5s was possible. Anything that could be done about traction like suspension, transmission?

I just noticed the additional info on your car
I agree, the 2.76 gears are a MAJOR handicap to any quick acceleration. I seriously doubt you would break the 7 second mark......sorry.3.91 would make a HUGE difference, but gear swaps are always a trade off/compromise

...do you HAVE traction problems now? If so, that's impressive with 2.76 gears?
...do you have sure-grip?

I should say that I just bought the car but don't have with me yet. I think it's the stock rear for the 73 charger se 400

I'm not %100 sure, but with a stock 400 in a heavy 73 Charger with 3.91's, maybe 5.5 or 6 seconds? You'd need decent traction, and probably a higher stall torque converter to get there.
Your goal is doable though I think. Especially if you go the 470 or even a 505 route since it really doesn't cost much more.
Speed cost money, how fast you wanna go?

Seriously? Drove From Memphis to San Diego with 4.10 gears and no overdrive.
NO PROBLEMS.
But it wasn't my momma's car I was driving either.

I'm talking warmed up to about 400 hp.

I'm not saying you can't, and I guess it doesn't bother some people. I have a '80 Mirada with 3.91's and long trips at 3500+ rpm and the loud exhaust get on my nerves after a while. I never had a problem but I guess I worry too much with the engine buzzing for hours like that.

Re: 0-60 in 4 seconds - 04/07/13 12:13 AM
I eventually want to get to the 470 stroker but its too much money for now. So I'm getting there in stages by first warming it up with some heads, cam, intake exhaust etc.

Anyone knows of an acceleration calculator that takes gears into account?

According to Wallace my Duster's 0-60 is 3.71 (using my best pass.) I have never calculated nor even thought about my 0-60 time before, lol!

I have been using this one but obviously there are a lot more variables.

How warmed up a 400? The 400 in my '71 Charger is stroked to 500", I think it may be around 4sec 0-60

Re: 0-60 in 4 seconds - 04/07/13 07:54 AM
I think you're in the high fives with a warmed 400. Asking a lot to be in the 4s without some serious heat.

0-60 times are for the magazine readers and bench racers.
nobody cares about 0-60 until you start reading R&T, C&D, MT, etc. and they're trying to give you specs on the latest and greatest sports car to hit the market.
real racers care about 60' times. 1.6 is good. 2.3 is not.

400HP from a 73 400 is more than warmed up. Warmed up is a header, intake, carb, small hyd cam (less than 230*@.050). 350Hp is more realistic.
The 2.76 gear is fine, IF you have enough motor.

Was going to add aluminum heads to the combo you mentioned maybe that's not considered warmed up, but would the combo you mentioned plus aluminum heads get me closer to 400 hp?

What do you think the 60' time would be for the package I am describing?

Re: 0-60 in 4 seconds - 04/08/13 01:27 AM
Sixty foot time is the number most associated with chassis efficiency...aka hook. It's the quarter mile elapsed time (ET) that matters. A 12 second car will generally have a sixty foot in the 1.6-1.8 range.

I had 3.55's in my 5th ave and hated it....cruise at 75mph (5 over on the freeway here in MI) was ~3200 RPM with 27" tires and lockup tranny. my exhaust wasn't too loud, but my ears were ringing after 1/2 hour....adding an OD helped a lot (A500)
FWIW, a stock brand new charger R/T 5.7 will pull ~5.4-5.6 0-60 and 13.5-14.0 1/4 mile time...a brand new SRT8 charger will be about a second faster in each....
it would take a very pretty warmed up 400 with some deep (3.91-4.10) gears to match a stock brand new R/T...
if you still want it drivable on the highway, I'd look at adapting an A518 (46RH) tranny--the .69 OD would make 3.91's feel a lot like your 2.76's on the highway, while increasing your first gear torque multiplication by 42%

Bragging...I have been .910 to the sixty foot timer many times.
and to 100 mph in 1.1 seconds, not 1.2 but 1.1 seconds.
So I guess that's about .6 tenths of a second to 60 mph.
Can you imagine getting on the freeway with that much speed?
0-265 mph in 5.49 seconds for me personally.
Oh yea the hemi is 12" behind my head, it's kind of loud.

Ok so more like 6 seconds with aluminum heads, cam, intake, headers, exhaust?

Go find some "back in the day" articles and get real. A 4000 lb car with a 400 is going to have a hard time breaking into the 6s without some really good engine and chassis work.
Put a stock '73 400 on the dyno and you're looking at well under 300 hp.
Just sayin'
