Just random guesses; it is from...
 

...ship, dragline, locomotive, off road mining truck and it bent from running over 800 rpm?

Pratt & Whitney, Wright?

I was thinking the same thing f****** CMI leaked and hydrolocked the piston.

Hey, why take time to read the actual thread subject. :poopoo:

I was wondering if Cobra built 5000 cubic inch engines .....:lolhit:

slow speed cross-head diesel ship's engine, could also have been in a powerstation, cool pic!

Should have put a tarp from a baseball feild in the intake an set a truck on top of it. oooops. Lol

----What,,,Theres something wrong???........Bill S

Looks like they removed one rod bolt with a crane. After burning the other 36'' rod bolt with a torch. Bad CMI Merc headers for sure. Remember to find the problem before replacing parts. An as You can tell, The motor was fresh. Hehe.
