Good thing my wife bought me one for Christmas!!



I guess I should start a new thread about my new motor instead of hijacking this one.... My appologies Mr. bnehila.

Please tell me you're not really thinking of swapping that POS into a truck

POS? Out of respect for my fellow f150online members that might have the "other" brand diesel motor, I will refrain from making powerjoke comments... And yeah, its going in the black truck...

I'm referring to the electronic 8.3L CDC engine. I don't really care if you're replacing a PSD or not. I don't even own a PSD anymore since I went Cummins. All I can say is have fun with the CAPS pump on that thing. I've got one on one of my test stands at work and its quite the POS. The fuel economy on them is also in the crapper. You'd be MUCH better off with a mechanical 8.3L or a later model 9.0L, though you'd hate the fuel economy of the 9.0L even more. Theres a reason we don't use them anymore. I can give you more specifics if you really need, but repairs on that engine are NOT cheap and it WILL happen.

FYI, that engine was originally made by CDC (Consolidated Diesel Corp), which was a joint venture between Case and Cummins, so yeah I've got some experience with them.

Put in my 4.30s today. From 3.73. Only 250rpm change at 50 mph. Should have went more!

How do you find out what rear end gears are in your truck. I just purchased a 2004 F-250 V-10. I am getting 12.2 mpg (actual) my computer says 11.6 (Lariat trim)
thanks

There is a tag on the rear axle or you can take the VIN to the dealer and ask them to tell you.

Jack up the rear axle. Put a mark on the tire and a mark on the driveshaft. Spin the wheel 1 revolution and count how many times the driveshaft spins. .

Much easier way - look at the door jamb sticker for the axle code.

If you are getting 12 mpg with a V-10, you are doing okay. That's about what they get.

Yea 4.56s would of have been a better choice, I had 4.10s in my old f250 5.4L with 4.10s and that thing didnt have enough power at all unless I had it in over drive and kept the rpms up. But hopefully those 4.30s will work out for ya.

They seem to be working out well. Need a little more power but rpms are good on the highway. About 2500 at 80mph.
