ooooohhhhh..... I'm really starting to hate your answers! But still appreciate your sharing of knowledge!
Complexity needle just hit the red zone.
OK. New plan. I have the engine so might as well use the ultra low mileage lower end. From everything I've seen, the blocks remain the same.
But it seems a shame to spend money on pre-PI heads. And a shame to put all this time and effort into the engine without getting at least a little power bump. So how about just upgrading to the PI heads?
Will my '99 pre-PI intake work on those? I've seen photos of both and understand the PI intake ports are somewhat larger but please, please tell me the '99 intake can be modified to fit?

That's good info to have!
Which brings me back to heads. This whole thing started because one of my heads is really buggered up - even a BigSert wouldn't work. So the hunt continues.

I think a PI swap is your best bang for the bucks and ease of installation.
Heads, Cams, and Intake.
You'll get a slight bump in compression which will raise power.
The cams will give you a slight bump in power.
The heads flow better which will raise power.
The intake will flow better which will increase power.
Get a tune to take advantage of the extra air flow and I believe you'll feel like you're driving a different truck.
Do you have a valvebody in the 4R100 yet? I'd throw one in there too.
And buy '03 or newer heads to get more spark plug threads. You probably knew that already.
I use car-part.com
They seem to have some of the stuff you need.
'03 Upper and Lower intake: I saw for $150
'03 Heads are around 250 each complete.

GET OUT OF MY HEAD, S.A.L.!
Just kidding with you. That is exactly what I'm thinking. Thanks for validating my thoughts.
As others have mentioned, I may not get the full 35 hp bump that the factory claimed with ALL of the changes incorporated in the PI engines, but it sure can't hurt.
I put the complete 3V engine up for sale. If it doesn't sell by the time I get the old engine ripped out, I will tear it down and use the short block and then sell the rest part by part. Keeping the starter/alternator/compressor for spares, of course.

Oh, and I do have the BTS valve body already as I use truck mostly for towing.
Another checking question: Does anyone know if there were any changes in the PI compatible intake manifolds from 2000 to 2004?
I want the 2003 heads for the plug threads, but want to keep the swap as relatively painless as possible.

Been following this and a few other sites because I too have a 99 with plug hole that no one will gaurantee a fix for. I'm thinking of an engine swap and would like the extra power that a newer one would give me. Whether junk yard or crate motor, I'd like to use a 03-04 motor because of thread fix in heads. Besides the head, cams, intake,and tune stated above, what other issues will there be? Wiring? Injectors? Plumbing? Current motor has EGR from exhaust manifold, can that be eliminated with headers at this time? Any input good or bad would be appreciated.

I THINK (don't know 100% yet, but based on several inputs, am pretty sure):
EGR: Physically, yes. Comes right off. BUT, I don't know about the electronics side and removing it will require adjustments to the PCM. Definitely discuss with a tuner.
Ignition coils: The data bases I've checked say the same ones (Motorcraft DG508) for all 2V.
Injectors: I am seeing a different part number for 2000+ versus '99. I have no idea what changed. Flow rate? Change in the connector?
However, I am thinking this should not be a show stopper as long as the tune and injector rail matches. And maybe the wiring harness IF the connector was changed. And maybe (long shot) fuel pressure regulator. I haven't researched that as I will be staying with '99 on mine.
If you haven't checked this thread,

It is worth a read.
