That's a rare/special car, weather you decide to install a close replacement now (or not) I would still recommend procuring the best/most accurate replacement you can find even if you keep it under the bench and decide to install something else. 1971 340's also have some one year only parts that you should also try to locate while you can (short list of larger items below).

1971 4972s Carter Thermo-Quad Carburetor
DR1114429 Idle Stop Solenoid
1970-1971 340 Air Cleaner
1970-71 Valve covers
1970-71 340 Oil Pan (294 stamped into the bottom)
1971 intake manifold- Casting # 3512100
Exhaust manifolds, casting #3418621 Drivers Side & #3418623 Passenger Side (the hard part is finding both with casting dates prior to your cars SPD)

You can learn more about correct parts details (Here ).

As far as a replacement 340 block goes your choices are pretty straight forward, most opinions will vary but the following are my personal choice list, my most to least favorite in order:

1. Find the original numbers matching block (long shot but nothing else will be 100% "correct" )

2. 340 block, warranty replacement or service block. I like these because the casting date doesn't matter so much and it won't have another cars VIN sequence number on it.

3. 340 block from another car which has an assembly date before and close to your cars scheduled production date.

4. 340 block from another 1971 model year car (any date)

5. 340 block, any year casting you can find

6. 340 block, new Mopar replacement "Resto 340" block

7. 360 block, any year
