97 f150 4.6 engine spec's???
 
Where on the internet can one find ACCURATE ford engine spec's for the 97 f150 windsor?
My oem manual can be confusing.

Exactly what specs are you looking for?

Try this site Rebuilding The Ford 4.6L: Engine Builder

I have only just looked at the site listed above and will read it later. I does have a lot of useful inormation from what i have seen so far.

Well, I bought the book....rebuilding the 4.6/5.4 engine by georg reid but their subject engine is using oversized components and it refers a lot to those parts, not standard size engine components.
My ford oem manual is full of errors and is a bit confusing, (i'm not a engine builder).
I'm just trying to gather the most complete and accurate info I can get.
I'm sure I could use my manual and get it done but a second and maybe third opinion is better.
Torque, cylinder wall to piston clearance, cylinder taper etc.

Torque, cylinder wall to piston clearance, cylinder taper etc.

I posted some information earlier and it doesn't show so I'll try again.

I looked through my service manual and cannot find engine clearance spec.s for the later engines. I'm quite sure I have them in my Mark VIII manual and although they are for a 4.6 DOHC they should apply to your engine.
It seems that Ford either doesn't trust their techs to rebuild one of these engines or they do not want anyone else to be able to, such as rebuilding shops that compete with them in the sale of Reman engines, short blocks and cylinder heads.
In any case here are the torque specs, again.

Thanks moto mel.

Actually, my 97 oem manual has these and the machining spec's.....it's just that I don't trust all of it since there are errors thru and thur.
Like, what's the correct cylinder wall taper for these 4.6's?
Using the standard oem "hypereutectic pistons" that these engines came with.
The reason I'm harping on this is because I may attempt to rebuild mine or maybe find another one I can work on while watching my engine rack up the miles.
All of the used engines I go and look at have some serious vibrations on the motor......I can actually see the engines move side to side a good 3/8".
I go home and look at mine and at 340k miles it runs so smooth I can't even tell it's running.

My hard copy '98 Lincoln DOHC manual has the specs but you do have to be very careful when using any manual or any source other than the engineering data sheets. Bore taper is a critical dimension and with the hypereutectic pistons you have to be at .0002 taper or less as the piston to wall clearance is very tight. Forged pistons require more clearance due to the rate of expansion but taper is still very important. I suggest that you have the cylinders done by a shop that has a very good reputation and late model machinery. A Sunnen Hone is the best for top quality bores, depending on the machinest of course. You could have them show you the taper with their bore guage both before they do the job and again after. This would prove bore size and taper. They should not be unwilling to do this for a customer.
