Oh yea, lifters can be replaced , best if you replace cam an lifters together ! Loud knocking is not usually associated with lifters , they usually make a ticking noise ! Knocking noise is most usually in the bottom of the motor , main or rod bearings . most of the time rod bearings !
Have your valve lash adjusted. Overhead cams need the lash done every 25-30K otherwise after some time they make a loud ticking sound. If the motor makes a "Knocking" sound, it may be a lower end noise, and there is no adjustment for that.
the knock sensor changes the timing of the motor when it senses knock ,it sounds like the wire may have come off ,it sounds as if when you press the gas the timing should advance and it sounds as if its not advancing thats why you are hearing a clattering noise on accelerating.if you keep driving it like that you can do engine damage
might be the valves have been damaged running without oil
- or the crankshaft / camshaft / main bearings
most probably you have to let the engine be rebuilt by a mechanic
(expect cost of more than US$ 2.000)
or get another (used) engine at a scrapyard
No I would not chase to the pistons, these vehicle were very comon in creating HLA noise hydraulic lash adjusting valves, meaning the valves pump up with oil as the oil gets thinner they dont pump up as fast and create a very loud ticking noise, I would not express a great concern over simplicity, dodge was famous for this, they really were.
Check the oil! A ticking noise is most commonly a sign that there's a lack of oil running through the motor. Start the car and listen for general vicinity of the ticking noise. If the oil is fine and the noise is coming from the engine, there are oil additives that will quiet the noise. Ticking is also a sign of an old motor (guessing you have about 150K on this car) I hope this helps clarify your problem and wish you well with your car. All the best! Greg p.s.

how is the oil level and pressure?, how many miles on engine? is this a loud knock or rather a clatter/ticking noise? knock is engine rod or crankshaft bearings, clatter loud ticking is valve follower noise. how long before it (the noise) goes away?
