Brad, two questions for you:
1. Is there any good reason to use the 3L heads if you have the SVT 2.5L heads??? Is this the reason why Terry Haines was talking about the 3L Long Block (almost a direct drop in and ya don't have to slap all of the old 2.5L stuff back on)???
2. Will the SVT ECU hold this new 3L beast back from its full potential???
1. Going to have to come up with your own answer here. Use the 2.5 heads if you're cheap and on a budget and don't have access to SVT parts. The SVT cams(if you have them) can be modified to work with pre '01 3 liter heads, or used directly in the '01+ heads. Use an electric water pump (many discussions on thie topic) if you use the pre '01 heads. Use the factory WP if you use the 2.5 heads or the '01+ 3 liter heads.
2. Yes. Needs to be custom burned chip or have aftermarket manual adjustments made via fuel and spark computers. Will it run fine without it and not throw a MIL? Yes, but not up to full potential.
