hi guys ! i wanted to know what is the best time ever recorded for a 340 duster or demon .. bone stock ... i know that they used to do the quarter mile in 14 sec but a lot of people said to me that a lot of was capable to enter the 13 sec range ???

thx
 
I was going to ask what year but I guess that would be part of the question....Im sure it would be a 1970. I don't know the times.
 
I know this isn't the answer to your question, but I ran a best of 14.28 at 98+mph in my '69 340 Swinger back in early 1970. This was bone stock with a 727, non-Sure Grip 3.23, and stock exhaust
 
ocdart...how and the heck do you remember that? I'm not even forty yet and I can't remember my times in the mid 80's!

amazing!

Aloha!
 
I do have the info on how slow a 340 can be....

Those 72' Model cars are pretty sad.....todays' Sport Compact four cylinders would have a hey-day with those "Muscle Cars"....hell my 200hp 2.0L Turbo AWD Eclipse went 15.0 @ 90 bone stock through a paper air filter.
 
as far that i know there a big big difference on a 70-71 340 duster and my 360 police pak 76 duster ... i have to change everything .. to perform like a 71 !!
 
I had a 1970 340 Duster. My Dad ordered and bought the car new from Bill Swad Chrysler Plymouth here in Columbus Ohio for $2375.96. This is a list of what he ordered on the car. 340, 275 hp. with 340 lb.ft of torque, Carter AVS 4bbl cast iron intake and windage tray and 10.5:1 pistons, 727 trans, dana sure grip with 3:23 gears, Disc brakes, power steering delete, alum. water pump, and steering box, dual exhuast, bench seat, air delete, column shift, bias ply e-70 14 tires. the car was black with stripe delete and black interior. He sold the car to a co-worker in 1974. I bought the car back for $500.00 in 1978 with 98,000 miles on it. I did have to replace a push rod and had a repaint but that was it. I took this car with slicks to National trail raceway on easter sunday in 1978 sunny and 68 deg. I put it in drive and went 13:28 @ 105 mph. and still have the time slip to prove it. My friends were amazed that this car was TRULY bone stock except for the slicks. Life got in the way and so went the car. But as far as I'm concerned for the money in 1970 the Duster 340 would put many more expencive cars to shame and I wish I never sold it. Thats me and my Duster at JCPenny outlet on a friday night in 1980. Thats where we used to race.....Shhhhh....lol

One BIG problem is, "you cannot trust the old magazine times."

One day, during a break, I was leafing through a car mag somewhere between 70-74. I don't remember which one, but it was a popular one, "Hot Rod", "Popular Hotrodding", "Car Craft," etc, etc

WAY in the back of the mag was a box similar to an advertisement

It went something like this:

"XXXXXXX Magazine admits we sometimes "factor" car times and trap speeds. This is because we often test vehicles under less than ideal conditions, and tires, weather, or maybe the car was a beat "demo" mule, etc, leads us to believe "the car" could have done better. We apolo...bla..bla. bl bla bla bla."
 
My best friend ordered a new 1972 340 Duster, 4 speed and 3.23 SG. When Spring rolled around we took it to the strip and he made a few passes. Other than larger G70x14 Goodyear Polyglas white letter rear tires, the car was pure stock with about 5000 miles on it. He made a couple passes and it ran 14.51. (I don't remember the MPH) Then dumbass me, thinking I was Jake King, took the distributor apart to change the advance springs. I didn't get it back together in time and he missed the class call. And to make matters worse, I was going to drive it next, DOH! That was the only time he ran it before he bought another new Duster, a black 84 with a 318. Then he fell off the edge and went back to Chebby after that.

1972 was the first year for the low compression 340 and I always thought his ran pretty good. If I had to spec out the fastest factory 340 Duster, I'd say a 1971 T-quad 340 w/ 3.91 gears. IIRC, the 71 's were factored higher than any other because of the big carb and high compression.

Bone stock 72 auto ,in drive with 355 and 275 radials 13.98. The Time slips before we bought it were in the mid 13's. My son could not get it hooked up. It took him 4 passes to finally get that time. worked his way up through the 14's. last pass he let it shift on its own. I guess he is use to turning right and sliding left. a good running 70 would go low 13's but not with him driving it.

Not to mention the driver can make a huge difference,either way. He could for example,do a burn out and smoke the clutch,then go do the 1/4 run and not even know the clutch was affected.

Or just plain bog the car off the line..
 
In August of 1970 I bought my new, off the showroom floor, 70 Duster 340. It had a July build date, one of the last 70 production models. It was a 340, 4-speed, 3.55 suregrip. With just minor carb rejetting, and distributor recurve, I ran consistent 13.90's with the stock E-70 white stripe polyglass tires. All of the other 340 cars, at this track had headers, cam change and tires to get the same times. A couple of years later, I put a 440 in the car. We tore down the 340 to see if we could find out why it was such a freak. That's when I found it had the 340 TA motor with the 4 bbl intake and carb on it. Oh the joys of a end of production year car.
Here's a pic of the car, taken in 1975...

the 1/4 time depended on gears and tires- from being there in the day- 3.91- 4.10s were the hot ticket-esp with 4 speeds... but I remember 340 autos with 3.23s that spun less and could run low 14s- and tough on the street
 
my wifes 75 Duster 360 which is "almost stock" which the only mod's include a 340 Cast Iron Intake, J heads (stock valve sizes), and a 340 resto cam runs mid to high 14's all day long with crappy tires and having to feather the throttle off the line
 
My brother had a 1969 Barracuda Formula S Coupe with a 4 Speed , numbers matching factory avs carb through the exhaust manifolds it ran 13.65 @ 107 mph. Thats about 6 tears ago when he sold it.
 
Back in the day when I was driving my 69 Coronet R/T I had a buddy buy a new 340 Duster, 3:23 sure grip, 3 speed manual. It would run high 13's to 14 flat in street trim.

Have any of you guys heard of the F.A.S.T. series that runs in the NE?
Some of these cars are amazing...ck it out, 71 Duster 340 11.27 @ 120 MPH
