Engine Tech / Re: 3.8L Mechanical Fuel Pump interchangeability ?
When I looked up 3.8L balance shaft on google, it shows 99-04 Mustangs 3.8L have balance shafts. Those are rear wheel drive cars.
What I'm trying to do is find out what takes to carburate late model 3.8 engines.

So, with out going back and reading your previous post...89-98 are not balance shaft ?   Sorry, to drunk to research at the moment.   Thanks by the way !
EDIT: Also, if 89-98 are not balance shaft...can someone just delete the balance shaft ? So in other words, just delete it ? Making the block emulate an earlier block ?

So I re-read what he was saying.  The cam retainer is different on roller cams and thus if you modifiy the cam with an eccentric, it will want to walk. Then he said something about making sure the distributor gear being strong enough to handle back fire.
Next, I researched  google about the balance shaft.  If someone were to upgrade to a high lift cam that made vibrations, would the balance shaft also have to be modified ?  That seems like a bunch of bull $#!T ...... the more I read, the more I like the old engines better.  It seems the 99-04 Mustangs have balance shafts, as far as I can tell at this point.  Not sure about the other years or models. I guess I'll be researching that next.

84 Shop Manual 5.0 V8 camshaft.
Fuel pump eccentric part # 6287

softouch, foureyedpride.com member "xctasy" said something about the cam walking on the later roller cam motors (89-04 ?).
 I'm not sure what he means there.  You seem to suggest the 5.0L eccentric will swap over to the 3.8L, yes ?    
Next, I'm still not certain what you all are talking about in reference to "balace shaft".  I'm guessing some 3.8L are internally balanced and some are not ?  My link on FEP.com mentions a weight on the shaft. I'm just not familiar with style balancer.
Last, from me buttstuffyzing all these comments, I think its safe to say that all 82-88 will drive the mechanical pump without any extensive modifications. All that needs to be done is cutting a hole in the timing cover on the 84-88 to fit the pump arm to the eccentric.   Is everyone in agreement ?

I'm not sure.    I don't have an 83 with a mechanical pump, but I'm trying to building one.
I've already bought the distributor, dura spark and intake.  Let me tell you, finding that intake is hard !  Even though you may find them listed at junk yards, I've contacted about 20 yards that had them listed as inventory, only to be told it was no longer available.  All I need now is the block, but I'm not sure if I can use later models, or not.

Engine Tech / 3.8L Mechanical Fuel Pump interchangeability ?
Hello, I'm curious if the 1983 carbureted Tbird 3.8L mechanical fuel pump will interchange with later fuel injected 3.8L blocks. 
If the last year for the carb was 83 and the first year for throttle body fuel injection was 84, I would not expect Ford to redesign the entire block just to eliminate the mechanical fuel pump. That said, it would only make sence to change the timing cover, or add a block off plate to delete the mechanical pump.  I suspect the year the Tbird switched to serpintine belt there was likely a change in the block, or atleast the timing cover.   Anyone know any details ?

Suspension/Steering / Re: 5x4.5 lug hub swap ?
One more thing, a friend of mine has a junk Cougar at his shop. Did the Cougar also switch to 4.5 in 1991 ?  If so, can I just pull those hubs and rotors and be ok ?

Suspension/Steering / 5x4.5 lug hub swap ?
My 90 Tbird LX 3.8L does not have 5x4.5 lug pattern. I went to install some later model wheels and found out the hard way.  According to Auto Zone parts number search, the Tbird went to 4.5" pattern in 1991.  That said, in order to get my new wheels to mount, do I just swap the hubs and rotors from a 91+, or is there more involved ?

Body/Appearance/Interior / Subframe connectors
I don't know about that. 
He only used the outer skins on the rear I think.
 If what you say is true where are the rear sections welded ?
Here is a pic of my 87 Turbo Coupe rear section.  Tell me how I'm supposed to get a straight piece of square tube to line up perfect.
