I picked up a 99 Ram 2500 2wd V-10 that more than likely has bad head gaskets (coolant in the oil). 175K miles on the truck.
The price was right and other than the engine issues it's a really clean truck.

Rather than just doing a tear down and head gaskets (and maybe a valve job) I've been thinking about just swapping in a lower mileage engine.
I've found a few with 65 to 100k on them and prices seem reasonable (in comparison to the price of doing the heads).

I know there are issues of swapping in an OBD1 engine and require sensor changes. (94, 95, 96 engines)
My questions are
"Does using other years create issues with fitment of sensors?"
Will the sensors swap right in and fit?

I tied doing an online search and didn't get any clear answers.

Thanks in advance!

I honestly can't answer your question. I know on some years and some engines the number of teeth on the tone wheel for the crank sensor is different. I don't recall if the V10 has a tone wheel on the crankshaft or if it uses a bellhousing mounted sensor like the 5.2/5.9 magnum v8's and v6's do.

Either way the crank and cam sensors are probably going to be your main issues.

use the upper intake on your existing motor,rest of sensors are the same
