Where can you find the HP rating on your motor? There are no stickers on the valve covers. From what I read , there are 3 different ratings, 155,165,185. This is for my '87 6.9. My pump is a DB2829 4746. Thanks
Oops, my bad. Not 29 mm. Not .029" either.
Let's try .290"
Funny. All I can remember seeing on the valve cover stickers was 155 and 165 for a 6.9. 185 for a 7.3. 195 for a 7.3T. Maybe I missed seeing a number?These engines were rated 170 HP.

I was thinking the same thing. I have a pump off my '91 7.3 that's still in good shape. I was wondering how it would work on my'87 6.9 project. If it smoked a bit, maybe turn it down a flat? Wes posted above that it would have some positive effect on the truck. Maybe Wes can chime in a little more about the subject?I assume that the smaller 6.9 pump is enough for a N/A engine and swapping to the 7.3 pump would just make more smoke.
This sticker above tells it all, each engine has a low and high altitude calibration. 52cc for a high altitude 166hp setting, and 185hp for a 58cc setting at low altitudes. You can see on Jason’s sticker the 185 is punched out, so he has a 185hp setting from the factory.Here is the sticker off my 1993 7.3 n/a maybe it can help
