Does anyone know what a stock super six with 2.76 gear in a 3300 lbs car at sea level would do in the quarter mile ?
 
I think the ET might be measured in minutes, not seconds...

automatic? 18's would be my guess, 60 ft would be dead. With a stick shift backing them up, you could dump the clutch at 4000 rpms and probably get a low 17
 
I think 18's would be fast more like 21 sec would be my guess .
 
2.76? Stay away from the track until you get a set of 3.23's. Then you might get a 16.9; go for 3.55's if you don't live in the sticks.
 
19.98 @ 64.96 mph in a '66 Coronet more door , auto with good air and a tail wind . Reached 64 mph @ 900 ft. out . lol
 
The answer won't be valid because the rotation of the earth becomes statistically significant and alters the location of the finish line at those levels of elapsed time.

Ha!!! Some things are not destined for the strip unles you want to spend quite a few bucks. It was still amazing to see a Mo. Toad run 10 flat and kick that HellCats ***!!!! Yep that NS Toad had many $ spent on his frog ***.

I want to say I was there for that....

I remember being not impressed when I put a Super Six setup on my Dart. I'm pretty sure it slowed it down.
 
but..... cut the head .100 and find the true 2" exhaust outlet manifold and run a 2 1/4" out the back, and that super six will amaze ya.... well, not really, but ya know what I mean :)

I agree. The right rear will make for a lot of "seat of the pants feel" too in a light car especially with a stick. Better mileage can be found with the super six if you drive good. The slants are what they are but can be improved no doubt.
 
best way to go fast in the quarter mile with a /6 is by finding a flatbed ram truck to put it on and race that instead

My 64 Dart super six four speed 3.55 Clifford cam ran 11.8 but that was at a eighth of a mile convert it over it should be low 17s 1/4 mile
 
I had a '72 Duster once with a slant auto. We put a super six on it, cut the head .100, mild bowl hoggin, 3.55's, and 2.25 exhaust off of the bigger outlet manifold.
I didn't take it to the track, but of all my trips to the track and experience, I say high 15's. We did race it "out of town" against a '91 Dynasty of mine that I took to the track and ran 17.20's. Wasn't even a race, the Duster tore it up easily.

the question should be why would you race a slant 6 w/2.76? Answer: For What!
 
I know what mine ran! 225 /6 with a 2bbl Super Six intake swapped on to it and an automatic.

Wait for it...

19.20!

By far the slowest thing I have EVER raced in my life. The car LOOKED fast and had a glasspack on it chopped off under the car so you couldn't see it was a single exhaust. We took shoe polish and wrote HEMI on the back glass in great big letters. I went right around the water box and staged the car. The announcer actually said, "Coming up next... WOW, a beautiful HEMI Duster." I heard him inside the car and was laughing so hard I almost forgot to leave!
 
Oh, and it did 69mph in the 1/4! That's right, merging onto the interstate was deadly in this thing. Topped out it did 115mph but it took MILES... at night... in the fog! That was scary lol.
 
My 65 Valiant with a 170, turned a 22.8 on its first pass. Fixed the throttle linkage so the carb opened all the way, removed the PS belt, loosened the alternator belt, pumped up the tires, and got a best of 18.9, that day. 5 years later the same car and engine (after mods) was running low 13's at over 100 mph, in the 1/4. In between as a NHRA legal stocker, could run mid 16's
 
I don't have a /6 car.
I was just asking. Cause 318willrun setup a plenty box system so us non stroker small blocks can race each other across the country.

I was just trying to see if the system held true for cars outside. Like /6 cars, big blocks and small block stroker kind of be different classes. Id think small block stroke would have the easiest time converting.

But one of you /6 guys with lots of experience took his system and modify it for slant 6 you could do a similar thing.

Ours is base on a 3300 lbs car with a 318 2bbl 2.76 at sea level 15.90. If the same baseline is kept probably could compare class and have an overall winner.

Add 273's, 340's & 360's to the "318 Race" ?
 
Such questions always bring out the haters w/ V-8's who shouldn't troll the Slant forum. A few slant 1/4-mile runs on youtube:
9.09 sec, www.youtube.com/watch?v=ZPm0POxQuNk
9.85 sec, (not a Mopar body): www.youtube.com/watch?v=-QeUq647mfE
61 Lancer (toad) beats a new HellCat: www.youtube.com/watch?v=GHkEidYitcI

The first 2 are w/ a turbocharger, which overcomes the small inlet valves. Bill Dedman's posts discuss that at length.
Of course, you also need big sticky rear tires, be willing to abuse your transmission and rear-end, have skill, and convert you car into something that is just a drag-racing toy.
