Advantages/Disadvantages - Thanks to Brad Noon for these.

Advantages for the 2001+ 3.0L are:


-The injector position is better in the 2001 intake/head design.
-The plastic intake conducts less heat to the incoming air charge.
-The water pump placement is similar to the factory 2.5 water pump placement, meaning fewer modifications to the hoses.
-The high velocity oval port design used along with revised intake cams provide better midrange power without the drop off produced by the older design at the RPM when the secondaries opened.
-SVT cams swap right in.

The Disadvantages for the 2001+ 3.0L are:


-The plastic intake can't take very much porting without fear of cracking.
-The heads don't accept the 2.5L intakes without an adapter plate.
-They're more expensive to buy initially than the older 3.0L would be.


Advantages for the '98-'99 3.0L engines are:


-Cheaper price (most expensive one I've gotten was $500 delivered for this year of 3.0L full engine assembly, including harness) allows you to purchase better than stock parts to replace worn parts for about the same price as the 2001 would cost initially.
-The 2.5L intakes fit the 3L heads without modifications.
-Using the 3.0L heads would require an electric water pump. Could be good or bad depending on how you look at it. For this case, it's good that you got a cheaper price on the engine itself, so that you can pay the $300 for the water pump and controller (never pay list price, LOL!). Plus you can have fun with the extra 5-7 HP that it saves in parasitic losses over the factory pump.


Disadvantages for the '98-'99 3.0L are:


-Higher mileage blocks may require more machine work to return to the road.
-Use of aftermarket water pump may be required, which involves a custom installation.

The 2000 3.0L has features of both the 99' and earlier 3.0L's as well as the 2001+ 3.0L's.

It features oval port single runner heads, plastic UIM/LIM, but does not use a cam driven water pump.
To do a straight swap with a 2000 3.0L one would require the use of a electrc water pump. It would be best
suited for a hybrid swap.

this doesn't appear to address the difficulty of going from a return fuel system to returnless. i know not everybody will face that issue, but it is noteworthy...

3L oval port head porting...

Go to my site.

Read the rest of the site too.


Real Soon I will be posting some of my scriblings too.

Just like I told everyone that asked.


The porting pictures are up now.

Pretty general descriptions. It may get more in depth if I get some free time.
