Mexico....we have a problem.

Looks like an overly abused engine to me.
Not from what the PO told me... driving down the road and BANG it stopped. Seen it before on these and Jeep 4.0's, too. Was in a Ram 1500... junked the truck due to rust issues and miles (190K).

No big deal really... this block will be the basis for my new dirt track motor (after I get my small block going over the winter). Likely 13/14-1 on methanol, using a 5.7 or 6.1 crank, Eagle heads, Pankl rods, mild port work, sticking with the juice lifters (new Johnson-HyLift), Jones cam, likely some stiffer pushrods, Ritter intake... just want to see what a reasonably priced Gen III can do for HP and reliability for 20 laps at a time.
