Need help finding a replacement engine; 02 4.7

[BAMABOY13]

Not new to Dodge, however I am to the 3rd gen and the 4.7. I bought this truck from a co-worker 2 years ago with 175K on it, just recently turned over 200K. The plastic side of the radiator blew out about 6 weeks ago, I replaced it, water pump, belt and hoses. It was fine until last week when I had a catastrophic failure; 1st; exhaust gas in coolant and coolant running out the exhaust. In an act of desperation I tried Blue devil. That stopped the exhaust to coolant mix but then the coolant to oil started mixing accompanied by knocking and clicking and very rough idle.

Can anyone tell me an approximate price on what a dealership would charge for a new engine installed?

But, I'm hoping to find a lower mileage 4.7 to replace it with, but in my search, I started seeing reference to VIN 8th digit # (mine is N). So do I need a specific N-code 4.7, or would any 4.7 from 02-06 fit? There is a Pull-A-Part in Montgomery & Mobile, but don't list any Rams in their inventory, but have several Dakotas & Durangos. If I go pull it the price is only $250 + core.

Which brings me to my last question; can I just hook up a boost box to read the odometer?

Any help is much appreciated

If you want a dealership to overhaul your motor you will find the price in the $5,000-$7000 range. If you wanted to go the remove and replace route with a salvage yard or LKQ type motor you will still be in the $3000-$5,000 range depending on the price the dealer has to pay to purchase the motor from the aftermarket/salvage supplier and then add their parts markup to it. If you have enough mechanical skills to go to the local Pick n' Pull and get one yourself, you can save yourself a ton of cash by performing the motor swap yourself.

Now, with the VIN codes, the reason for verifying the "N" VIN code is so that you know you are getting the correct engine with the correct crankshaft tone wheel.

Here is a quick reference:

The JTEC PCM's from 1999-2002(3-plug PCM) all use a 16-tooth tone ring.

The NGC PCM's from 2003-2008 (4-PLUG PCM) use a 32-tooth tone ring.

Thanks!
I just don't think I "love" this truck enough to go with a rebuild or crate engine. I just can't see putting that much into a truck that's not going to be worth any more when I'm done. Probably gonna go with a pick-n-pull, and then sell it.
Looks like I'm going to get one of my B250 vans going in the meantime.

A good place to start a used engine search is car-part.com You can search parts by year, make, model, and part and sort the results by your zip code. A lot of different junkyards all buy in to that website to reach customers. Id imagine your 4.7 to be about $1500 used with 100-150k miles on it. Just a guess.
