Engine block similarity

[rhabla99]

Does anyone know what years of the 5. 9 engine blocks are the same, (early years?} 89 to 97 ????

89 to 97 ???? YES with minor changes. First couple of years have some differences, then in May 97 they went to the "STORM" block ( Straight Thread O Ring Metric ) instead of pipe threads. This and later blocks ( including ISB -ie: 24V-98. 5-02 ) had a thread-in block heater (3/4 NPTF) and a second turbo drain hole. Why are you asking? Shadrach

I have a 93 W-250, I had to pull the engine a couple years ago, 116,000 miles , had a cracked block. I am thinking about getting another block and putting another engine together. So I wanted to know which years to look for That would work bolting all the 93 componenets to. Thanks!!!

I'd think any 12valve block from about 1983 to 1997 would work.

Just make sure it doesn't have a large number "53" cast on the side of it, as they were prone to cracking near the frost plugs under the exhaust manifold. Shadrach
