i had a few questions . first, i've got a 1987 xlt lariat extended cab, 460 7.5 liter. I was wondering how many stock horsepower and ft/lbs of torque it comes with. What type of axpes are in the front and rear (leaf spring front suspension). And lastly, I need to know if it comes stock with an oil cooler, tranny cooler, etc. thanx

 

Im not too sure but I think your truck should hava dana 60 front axle, A Ford 10.25 rear axle. Not too sure about HP numbers I would guess around 235 HP.
All the 460 motors I have ever seen in 87-96 trucks had factory oil coolers. Look for a adaptor above the oil filter with lines running into it. That would be a oil cooler.

 

As far as the axles are concerned, the f250's usually had the IFS Twin Traction Beams which is a modified Dana 44 with 8.5" ring gear. If it has a solid axle, it will be the Dana 50 with a 8.5" ring gear. The easy way to tell is that the TTB has coils while the Dana 50 uses leaf springs. the Dana 60 (9.75" ring gear) where usually found on F350 duallies. There were several rear axles available. (Not that you could choose though). The F250LD's have a Ford/Sterling 10.25 semi-floating axle while the F250HD (which you have) and f350's have a Ford /Sterling 10.25" full-floating axle. Some trucks had Dana 70 or Dana 70HD (10.5") axles. You can tell the dana's by a number "70" stamped on the webbing on the side where the cover bolts up.

 

I would assume you would have a HD F250 since you have a 460. so you should have a full floating rear.
All of the 250s I have ever seen with the twin traction beams had leaf springs.
I know the 4x4 f150s had coil springs with the twin traction I beams.

 

Yep, you're right. They do have leaf springs with the TTB. The F150' s have the coils, not the f250/350's.

 

Dana 60 straight axle was only in F350's of that year. No F250's got straight axles, they used the TTB frontend. The Dana rear axle was likely on duallys only.

 

OK, I found a more detailed lift kit and axle gear catalog that says the 4WD Bronco and F150's have the Dana 44IFS TTB on coils, the F250 LD (300,302) have the Dana 44IFS TTB on semi-eliptical leaf springs, the F250HD (351W, 460, diesel) and 86 & older F350's (I'll assume they are talking SRW here) have the Dana 50IFS on leaf springs (not straight axle, that's on 1999-2001 F250/F350 SRW Superduties) while the F350 Duallies have the Dana 60 monobeam.

 

n578md, What do I have then, I have a 90 F250, assuming light duty because of 6800 rating and semi floater rear end, But I have a 351.

 

The LD were bellow 8600 GVWR while the HD are 8600 and above. The 351W is definitly an HD. You most likely have a Ford/Visteon 10.25" full floater. If you remove your wheel cover, you'll see that you have a "round cylinder" sticking out of the center of the wheel (for lack of a better description). My truck has a 10.5" full floater and that cylindrical part sticks out about 4". That would be a full floater. The semi-floaters are flush with the wheel, nothing sticks out in the center. The semi floaters weigh about 80 lbs less and are rated to only 5300 lbs, while the full floaters are rated to 6250 lbs. If you look on your driver's side door jamb under AXLE you'll have a code there that's either 2 numbers for an open diff or a letter and a number for limited slip. The 6250 lbs 10.25" full floater codes are:

35 for 4.10 open diff
39 for 3.55 open diff
C5 for 4.10 limited slip
C9 for 3.55 limited slip

the 5300 lbs semi floaters's codes begin with a "2" for open diff and a "B" for limited slips. That's tell you for sure what you have.

 

Being a 460 equipped F250, it SHOULD (key word there!!! Doesnt mean things aint been changed) be equipped with a Dana 50 TTB in the front (basically a HD Dana 44 w/ bigger bearings, lighter duty F250s had a Dana 44) a 10 1/4 rear, oil cooler (possibly) in the radiator hose, and if it had a tow package on it, a tranny cooler. The horsepower rating should be 245 for the carbed version (230 for the EFI in late '87)

Also, a 351W does not always mean it's a HD F250. It depends on how the dealer/customer spec'd the truck out at the time of the order.

 

Huh, you learn something new everyday. I always though 351 and 460's were HD's only.

 

n578md, I agree with all of your axle info except for the part about F350 SRW's. All F350 4x4's, dually and single, from at least '87-'97 have a high-pinion Dana 60 reverse-cut straight (monobeam) front axle on leaf springs with a tracking arm from the axle to the frame. '87-91 have kingpins and '92-'97 have balljoints. I own a '92 F350 SRW 4x4 351/C6/BW1356/Dana60/10.25" full-float (see sig)... About the '80-'86 trucks, I don't know for sure, never owned one. Current Superdutys also have the Dana 60 straight axle on leaf springs.

 

It's pretty hard finding good info on the older ones I see. Thanks for the info though! The kingpin vs. ball joint would have been harder to find. There's plenty out there about the SD's that's for sure. The F250SD and F350 SRW had a Dana 50 solid axle from 1999-2001. (I had a 1999) The 350 DRW, F450 and 550 have the Dana 60 solid from 1999 to current as well as all 250's and 350 SRW from sometime in 2002 and above. I have a first printing 2002 Ford BBA book that still lists the 250's and 350 SRW as Dana 50.

 

I definitley have a light duty, 351w, The rearend is a 355 open semi floater. I was kinda baffled when I bought the truck a year ago and found 1/2 ton looking rear axles with 8 lugs.

 

BTW, which transmission do you have in it? (look at "TR" on the door label.)
