Fastest time with a 268dur cam?!

-
12.9/106 with a 2.2 60ft. Hughes HE 2430AL flat tappet hydraulic. 367/A833/3.55/ 3650#. No tune.Only complete run of 4. Very skinny street tires;245s as I recall. Hyup lots of tire-spin.Never been re-run
This cam specs out at 270/276/110, lift of.538/.549(@1.6arms). Advertised of 270/[email protected]
Super nice street combo!
 
Back in 1980 I bought a numbers matching '71 340 Cuda, 727, was a hot but stock street car with 3.55's, B&M SH verter 3500, 284/.484" purple hyd...dual plane and 750dp, small tube hdrs...that ran 13.2>3's@101 all day long with 26" slicks, drove real nice on the street with a nice lope and it pulled well to 6000, but I guess there's plenty of better cams today and no-one will want to run that today?.... it does need some verter., at least 2700ish min...swapped a few things around on it later and went 12.3@108 with the same block/heads.

Like it says, curious to how fast some of y'all have managed to go on a mild 268 duration cam. Wether it's the 268H, 268AH-10, XE268H from Comp, or any similar grind from any of the other manufacturers.

If possible please give complete engine specs!

Mopar Performance cam. Stock, low compression 360 with headers. RPM intake, 600 carb. Stock 904 and converter. 3.23 gears with 245/60/15 tires.

Same cam as shown in above post, 13.30's with 360, J heads, headers, 3.23 gears, 10" TCI street fighter converter.
 
256 @ .050 .547I .554E 1.96I valve, 1.60E valve. goes 10.80's in Vegas in our Duster. Iron head 360.
 
Quick 1/4 times begin with a good 60' time. You can achieve that with a good converter and some steep gears (4.56's or so) and a light car (under 3,000 lbs). MPH is a good indicator to how much power the motor is pushing.
Good example would be my low dollar 318 project that hit about 94 mph, but ran a 15.20. Lots of cars at 94 mph are at mid 14's, maybe even lower 14's. In fact, look at stock eliminator cars, look'n like they were shot out of a cannon the first 300 ft
 
My cam is 255/266 @ .050 , I have ran a best of 6.21 @ 110 in the 1/8 on pump gas.
 
The funny thing about that car is on the street it would waste just about anything it came against. Well 3.55s are totally wrong for the Qtr,(making it a 3-gear charge, and trapping at about 6100), but totally right for street. Top of first is 54mph and dropping the hammer at 30mph was about 3600;just above peak torque.....:)
Oh yeah, those Polyglass E70-14s? Hah! But that was what we had. And I was barely 18.

street is so different.... traction and all plays such a huge deal. 340 a-bodies were such a tough customer for so many factory muscle cars
 
Well for one thing we didn't suffer from massive wheelhop like the BBChevelles did.
No, we suffered from massive wheelspin.
By later that summer I had a handle on that, and while everybody else was doing the bolt-ons thing, I kept wasting them with my pure-stocker. My secret weapon was custom made slapper bars, 4.10s,90/10s and getting rid of those skinny Polyglass Es . Good-bye pure stock.Yeah that car sent a lot of comers home.
Oh man,those were horrible tires. I got into so much trouble with those hard useless donuts.But I learned to drive those before they wore out. And a lot of passengers have heart-stopping memories. That used to be the fun thing to do in high-school; line up two or three skinny *** grade tenners and pass the hat for gas, then we'd go for a spin. Hyup, a real spin all right. They didn't call me capital D-Ditcher for nothing! Just terrible tires. Rule #1; always blame the tires. Or the fat kid sitting on the wrong side of the back seat.....Or, Quiet back there!, how you expect me to concentrate with all that yelling and screaming going on?! And David quit yer crying, I told you not to come! But his daddy had money and so he did, and so he paid extra to get tossed around back there. He always sat on the "wrong side", and never in the front!
Now I dunno about you, but no way would I have ever sat in the back, where I couldn't see Death coming down on me, no way! I didn't ride with my friends, I always drove. Well, now, there was this one guy, but he was a rather sedate driver. He had to be; one more demerit on his license and he'd be walking.
