what to do about this??

id swap it

 

This truck isn't worth a large amount of money on the used market. Unless you can do the Cummins conversion without spending a lot of money. I would junk the truck. To rebuild this 3406B/C engine, it would cost more than the truck is worth in the end.

 

yep, look for used engine

 

If you can swap it cheap swap it. If not as Mr. Haney said scrap it. Just don't run it across the scale with the trans and rears on it. Those should still be able to fetch you a little money. And you've still got a b/c model core. Sounds too new to be what most guys want but ya never know. Might find somebody who wants to build a pulling rig out of that motor.

 

The only thing I would put a Cummins motor in is a...............scrap dumpster,or possibly a boat,but only for an anchor!

 

why not put a crank and new bearings in it.

 

The block was also damaged when the bearing spun in the journal. So the block needs a considerable amount of investment in $$$$$s to correctly repair the damage.
