Review This is a rare car. The steal in the 1991 350 SD is different than all the rest of the lineup that year being lighter gauge but higher strength to make the 350SD lighter and it was. If you have an original engine, it's a time bomb. It will happen, the bent rod issue. I had three bent rods in my "original" engine. Top speed speedometer indicated is 112 MPH with the bent rods and the engine needing a lot of oil all the time. I put a new long block in and turbo with the updated connecting rods and the oil consumption is normal now. Also the top speed is still 112 MPH. I was able to adjust the turbo boost pressure to 1.0 bar and this helped acceleration.
