Intake Manifold Swap?
I have a 93 Aerostar with a 3.0L v-6. It's got okay power, but could always use a little more for dealing with hills. I know that the newer 3.0 vulcan engines had composite intake manifolds and separate TBs, and was wondering if it would be an easy switch, or if I would need new heads and other bits.

The heads and block are the same with all the 3.0L vulcans. One thing you should keep in mind is that the intake manifold on a FWD vulcan (i.e., Taurus) is different than the intake manifold on a RWD vulcan (i.e., Ranger). The head gaskets are also different between the two.
If you are going to go with an intake from a newer Aerostar I think you should be all set.
P.S. You might want to think about porting and polishing the new intake it before you put it in.

You are talking about just the composite upper, right?
Apparantly, at least with regard to the Rangers, the newer "complete composite uppers from a '02 Ranger or '01 and later Taurus/Sable will fit. Make sure to get everything, intake, TB, air inlet hoses, clamps, throttle cable, etc. as these will make it a truely bolt-in mod." (Source) Personally, I would eyeball everything real good just to be sure If I was thinking about pulling one out of a Taurus or Sable.
As for computer issues, I am not 100% certain, but nothing I have read or heard would lead me to believe that you will encounter problems doing the swap you propose.

Intake Manifold Swap?
What is that?!?!
It looks significantly more efficient than the one I have on there now (doesn't take much though). Is it a custom made job, or some off the shelf part?

Yes, 100% custom. Had a machine shop make the lower plate and the throttle body plate and cut, fit and welded all the tubes myself. It is using a 60mm throttle body from 5.0. Best mod I have made to the truck yet. Bar none.

Don't know for sure. Had a dyno pull when I was still running the a4ld (on a 40k mile old tranny it only lasted 8k miles behind the stroker), and was not impressed. We had to cut off early because of the top speed limiter. He was using an iductive pickup for the dyno, and I am running an Accel 300+ ignition system with multi-strike below 3k rpm, so who knows if the numbers are correct or not. And I have heard so many different percentages on the losses through that tranny. A good rule of thumb is 20-25% with an auto, but the guy at the tranny shop I have always dealt with said the a4ld is a cheap piece of **** and could be as high as 35%. But at any rate, the dyno spiked at 170#' at 1800 rpm and then went flat at 150#' all the way across, and 130hp at the wheels at 5k rpm. So I am guessing it is around 200-220hp and 230-240#' at the flywheel. I am broke now and have not had the money to go back after installing the t5 manual. Does anyone want to take up a collection??

agelder,
This guy successfully swapped a 98+ upper intake assembly into his '94 Ranger, but the project turned out to be a little more than a simple bolt in:

On that note, I may wait until it is not a daily driver to try something like this 
Still sounds like a fun project. It would be nice if the Aero could get out of it's own way on occasion.
