Jeep Strokers

I started the tear down process on my Cherokee. My engine was knocking pretty bad. After removing the intake and header I found a window in the block near cylinder number 5. If there is anyone near san diego with a 4 liter block that they are willing to part with please let me know. Thank you in advance.

What is your cylinder block casting number?

I've got a 2000 4.0 block just over the hill in Reno if you want it!
