I have a very good friend who was a mechanic for many years at a car dealership in Santa Cruz, CA, and he was the one who told me the Duster is a 360..
70 Dusters did not come with a 360. That engine wasn't introduced until 1971 and wasn't available in the Duster until 72 (very rare). It replaced the 340 in 74 but the Duster was larger and all the emission control crap was killing the engine performance. Most drag racers preferred the 340 because it had a better bore and stroke and produced more net horsepower than the 360.
I bought the Duster from a guy at Mountain View Auto Interiors, and he had won 1st place with it at Cherry's Jubilee in Monterey, CA. It had been totally rebuilt from bottom to top, and the only thing I needed to do was put in an overdrive, because it was really loud on the freeway in 4th gear. I did have to have the engine rebuilt, but that is another story.
They had to put low profile tires and rims on it to keep it on the road, but the Duster was perfectly dependable to drive.

I guarantee you, if it was a 70 it had the 340 and not a 360. AND.. it was a rare gem of a car with the 340. Only about 20k were produced. Most had the slant 6 or 318 engine. At first I thought, it's possible someone could have thrown a 360 in it but if you say it won 1st and Cherry's, it's definitely a 340.

I didn't win it. The guy did.
The competition he was in I don't think was mechanically related so they for sure didn't check.
They had a lot of trouble squeezing the new engine in and it was probably a modern upgrade.
The Hemi was a 426 cu. in. with 425 h.p. and it was not available in the Fury, although it would fit if you put it in yourself. Same with the 440 cu. in. with 375 h.p. And the Duster was definitely a 340 cu. in. with 275 h.p., not a 360. It even says 340 on the side of the car.The 425 reference is likely horse power from 426 motor. But unlikely a fury had the hemi. Likely a 440.The Duster was a 340, not 360, and Plymouth didn't make a 425, they made a 426 but as I recall, the Fury only came with a 318 or a 383.
I have a very good friend who was a mechanic for many years at a car dealership in Santa Cruz, CA, and he was the one who told me the Duster is a 360 and the Fury a 425. Both my Duster and my Fury easily went 140 MPH, and IMHO the Duster couldn't have done that if it was a 340. I have never been mechanically inclined in the least and can only rely on what I have been told and heard on the forums and from people I met while driving the Duster.
The Fury was modified by the owner who probably was a policeman since it had a pass sticker on the window from around 1973. For a long time, I thought the pass sticker was from the CHP, but someone set me straight on that.
The 340 was actually a bored out 318 and the 440 was a bored out 383.

Well you said the guy won 1st place with it at Cherry's and I am familiar with Cherry's Jubilee in Monterrey. They didn't give it 1st place with a replacement 360. And yes, they DO check.
I'm not calling you a liar, I just think someone is confused. The 360s were mostly seen in Dodge trucks and the Polaris before 1972. It is a bigger engine than the 340 and the 340 would barely fit in the small 70 Duster.

Unless he won 1st for most atrociously dumb ass conversion, I am saying it was a 340.
The 340 Dusters were works of art... why would you drop a truck engine in one? Doesn't make any sense to me. I had a friend who owned a 70 Duster with a 318 and that was a huge engine for such a little car... he had trouble getting the spark plugs in and out. The 340 was the same engine bored out. I can't imagine the larger 360 even fitting a 70 Duster without major modification... and again, why would you put a lower torque truck engine in a Duster? The 340s were lighter and had more horsepower and were much faster in the quarter.

Would the 340 or the 360 be more likely to get it up to 140 MPH?
340.It wouldn't make sense to put a 360 in it. The 340 was a better engine.
Boss said a 340 would be better for a drag race, but for overall speed, which do you believe would be faster?
A side note, if you want better top speed, put a smaller rear end in it.340.It wouldn't make sense to put a 360 in it. The 340 was a better engine.

Dude, look at the stripes: the car is a Duster 340. The first 360 Duster was 1974...the first 360 was made in 1971. The engine pic makes me think it might have been built with a 318 or a six.
Chrysler never had a 425ci engine. They had 170, 198, 225, 273, 318, 340, 350, 360, 361, 383, 400, 426, and 440...no 425. A police fury would probably have a 440...otherwise, it could have a 225, a 318, a 360, or a 400.
