Hello,

I am currently running GT40P heads, upper and lower intake from a 1997 Explorer and the 19lb injectors from the same. It is more or less a direct bolt on situation with the only special part needed being the headers. To my understanding the stock headers will fit but the spark plugs will not be accesible so that is the reason for needing "P" specific headers. There are some posts on corral.net for regular headers that clear the plugs with the "P" heads. The lower Explorer intake does not have the provisions for the ACT sensor, you have 2 options here. Drill and tap #5 intake runner ( some of them have a place for this, others do not), or you can put the ACT in the intake tube right before the throttle body ( which is where mine is) or like the SN95 cars in the airbox itself. The upper has alot of vacuum tubes coming from the under side of it, I had all except 3 welded shut, little one for fuel regulator, and 2 bigger ones for PCV and brake Vacuum. I have used epoxy to fill them as well, and I have seen really rigged situations where hose and silicone was involved but I would not suggest it lol. I just switched the injectors, I had stock 19lbs and switched them to the new 1997 4 hole design ( I believe they are refered to as GEN III injectors). I would suggest doing this on any stang, as they are more efficient, atomize the fuel better, resist clogging, and give better driveability. I know this as I just did the swap this past weekend and my car is like a totally different vehicle now. As far as the Explorer throttle body, some mods need to be done with the linkage to get it working properly. There are 2 kinds of Explorer intakes to look for, one has EGR provisions the other does not, neither have smog ports in the heads and neither use thermactor plumbing. That is the reason they will not pass emmisions test on older stangs.

Other parts to look for,

24lb injectors on 460 EFI motors
Lincoln Mark VIII electric fans
Rear gears on truck as they usually are numerically higher
new style 4 port injectors, they are skinnier than the stock stang parts. As long as they have the same square plug for the injector harness they will work.

Oh and not to brag or anything but the local pick and pull sells complete engines for $150, that includes all accesories.
