Can you ID this motor?

[281Ranger]

It's a 4.6 dohc from a '93-early '97 Lincoln Mark VIII. Looks just like the mine did before I put it in the Ranger.

It's the same basic motor they put into the '96-'98 Cobras. Differences are the intake, crankshaft (cast vs forged), and the Mark's exhaust cams have .010" less lift.

Yup I 2nd that now.... found this on e-bay http://cgi.ebay.com/ebaymotors/1993...007QQitemZ170172989733QQrdZ1QQsspagenameZWDVW

so how much is she selling it for?

Don't forget that the continental engine has a different bellhousing from the RWD engines used in the Cobra and the LincolnMk8

After reading this:

She might not be! I'll have to check with her and see if I can find a place to store it until this 2.8 dies for good. I got to much money tied up in the 2.8 already to stop on it.

Say don't those Lincoln motor have an aluminum block?

Will is most definatly correct.The later Tauruses (the '96-up taurus) were powered
by a UNIQUE narrow-angle V8 that was 3.4 liters displacement

NOT a 90degree 90degV 4.6.

Well, learn something new everyday. I've always assumed that they were 4.6L based on the Continental. Still, they were a fun car to drive. IMHO better than the V6 Yamaha engine SHO.

its prolly a 4.6 out of a rwd, continentals were fwd n had the ps res on the fender, it culd also be a 5.4

Nope... the rwd 4.6s have the ps res on the fender. I know this 100% without a doubt. The res withs above where the control arm bolts on in the front. I had a really fun time doing brake lines coming out of the abs control on a few of those. And have also replaced a ps hose on some.

The 3.4 SHO V8 was nice until it broke.

Though the engine has a MAJOR problem.

The cam sprockets are only located on the camshafts by FRICTION
(No KEY!!!)
And many of those engines when driven hard would slip time bending valves break pistons and basically destroy the engine.

In other words they used a flawed attachment "scheme" to hold the sprockets in place AND as an additional insult to injury did this on
an engine that was "non freewheeling"

if I understand someone else's description
The "fix" involved "tack" welding the cam to the sprockets
with the timing set correctly, then disassembling the enine and
TIG welding the prockets firmly to the cam.

I once had to make a "fix" to a twin cam saab engine where
the original design used a sintered metal cam sprocket
and the key could (and did) shear off the exhaust cam sprocket
bending all the exhaust valves...
My "fix" was done to a NEW sprocket after replacing the valves
I drilled a pilot hole through the sprocket and into the cam
then installed a solid steel PIN into an interference fit hole
in the driving face of the cam.

the sprocket was then mated to the cam with BOTH the
original cast-in "key" and a solid steel pin about 180degrees around the face of the sprocket.

And that pin wasn't going anywhere because it was actually
located UNDER the head of the bolt.

I'm not sure I;d go through all that ion a V8 taurus engine
because in that generation of taurus they never offered a manual trans
and the performance difference betwene the SHO3.4V8 and the optional twin cam 3.0 v8 wasn't that great anyway.

Frankly I've driven both and if I could choose I'd take a '94-95 Yamaha V6 powered SHO with a 5sp.

the onl better highway cruisers I've ever driven were (2nd place)
a 4.6SOHC t-bird ('94-95) or (1st place) a Lincoln Mk8.

The Mark VIIIs (rwd) have the ps res on the engine. I believe the Cobras did too.

JoshT,
All 4.6 dohc engines had aluminum blocks. The sohc motors didn't get one until they started putting them into the Explorers. The only 5.4 aluminum block is in the Ford GT.

The '93-'98 Mark VIIIs and '96-'98 Cobras got what's known as a Teksid block. They were cast using a process that makes the aluminum less porous than a standard casting. The Teksid blocks are much stronger and about five pounds heavier because of this process. Guys have pushed these blocks to 1000hp with no work done to them. They also have 6-bolt (cross bolted) mains. Kinda shuts the Chevy guys up when they're bragging about 4-bolt mains.

I wouldn't give the lady more than $150 for the engine. The U-pull yards sell them for that and a whole Mark VIII can be had for $500. Besides, you know nothing about the history of this engine. It could be in his shop because there's something wrong with it.

As far as putting it into your '84 Ranger goes... it's not a bolt in. You'll have to change the steering just to get it in there. Do a search and you'll find threads with pictures and links.

Ranger ain't the only potential project for something like this. Actually I would be more likely to put it in something a little more classic (think 60's muscle modernized). That is after I completely went through and built it of course. If I'm not mistaken that engine is similar in size to an FE big block motor, weighs 200 lbs less, and has much more potential. I was figuring on building a fuel injected 390FE, but that 4.6 should fit just as easily, be more reliable, have a bigger after market, be more streetable, and is already set up for fuel injection.
