Before you purchase, run the serial number by Caterpillar. The 3116 was the Caterpillar that had issues with the block. I did not buy a 1997 MS350 with a 3116 after I ran the number thru Caterpillar. The sequence of serial numbers for that year fell in to the sequence that had trouble with the block. After about 800hrs one or both of the front cylinders would develop a crack. The engine would start to smoke and loose power.
Just a heads up.
