ON a 03 3500 single axle I cant find any info to tell me if it is a High Output or a standard .. Where can you find the info..

 

Look for a sticker on the drivers side of the valve cover, it will tell you...

 

The SO will have 235HP listed (California) or 250 everyone else. The HO will have 305HP listed on the tag...drivers side like tryNto said.

 

VIN #6 =S.O VIN C = H.O this is in the 8th postion of vin

this is H>O C in 8th http://cgi.ebay.com/ebaymotors/2003-...item3a560d5f24


This is S.O 6 in 8th http://cgi.ebay.com/ebaymotors/2003-...item3ca86465b5

 

Thanks for the info...

 

if a manual tranny the 5 speeds are SO and the 6 Speeds are HO. Just more info.

 

And I thought the SO was only avail in the 250s and all 3500s were HO. Oh well, Merry Christmas.

 

No It depended on what state you bought truck from MA, CA, ME could only sell the S.o till the 04.5 came out

 

Thanks ... Mine is a SO

 

Hi, my name is SOHappy and I own an SO Cummins Turbo Diesel too.

(they say admitting you have one is the first step.)

 

SO (no pun intended) if a truck has the 6 (meaning SO) and it was origionally sold in TEXAS....it would be a:

SO with the 250 hp....not the 235 hp sold in MA, CA, ME correct..

and further on that line of thought...

it would not have the CAT or EGR equipment required for the SO 235 in MA,CA,or ME....

please let me know I am in the market and do not want to deal with the CAT or EGR...cuz CALIFORUBA or CALICOMMIE which ever you want to choose is now SMOGGING these trucks.

Just look for the CAT or for signs that there may have been one there before. The sticker on the valve cover is the easiest way to tell for sure.....

 

absolutly agree that is the easiest things to do or look for....

but it is hard to do when looking at a truck 1500 miles away, pictures usually dont show the undercarrage and trusting a salesman to actually know anything about a motor is like trusting the devil to know anything peace, love and kindness..lol

can i look at the vin on my truck as well and do the same thing to figure out if it is an HO or SO? and mine has a cat on it. do i need to keep that on there?
