I want to swap my engine out for a newer and or one that's compatible.

No. Your best bet is to have the stock engine rebuilt, but if that is not an option then look for a crate long block that you can put all the electronics on and put that in so the computer can use the same calibration it was programmed with.

K. My timing chain has gone out on my 2006 dodge caravan se. I want to replace it with a metal timing chain or kit. Now, with that, do l half to replace the waterpump as well?
