Sad News
After looking at numbers and facts that my truck has, I finally found out what has been making me scratch my head so much. The truck has the number 7 vin and the 6 speed. But the engine has the 235 HP rating on the dataplate. Making the engine a S.O. engine. All this time I thought for sure it was the H.O. :argh: So the engine has been swapped. I know the power numbers from each engine but are there any benefits to the S.O. I don't realize?

Higher potential from an SO Injection pump than HO.
Compression is a little lower, but that's all the difference really. |
SO engines make power more easily, and will tolerate higher boost levels before having HG issues...
though you may have an HO motor with a SO injection pump... then again like my truck, not all 6-spds came with a HO motor...99.5-00.5 trucks with a 6-spd are SO motors which is nothing to complain about as it is great for making power!:tu: |
Well that's good to know. I know for a fact its not the original engine though. I am able to get on Cummins website and enter the engines serial number and see its a 01 engine. But the vin for truck it was installed in doesn't match my trucks vin. So its not original. No big deal. Its still gonna continue to get modified.

how would I know if mine was an HO or SO
|
Look at your trucks vin # and if the 8th digit in the vin is a 7 is a H.O. Then look at the data plate on the engine. If it is rated for 245 HP its a H.O. engine. If it says 235 HP it isn't. The dataplate is on the left top corner of the front cover under the engine.
---AutoMerged DoublePost--- Of the engine. Not under it. Lol. |
I looked and the VIN says I have a HO but I cant find that data plate
|
Its basically on the corner above the injection pump.
|
so it turns out I have an HO, what are the pros and cons
|
From what I know u have a little higher horsepower and torque and a better turbo.
