Ford guys, let's talk 2000 Ford Explorer 5.0 Fuel injection 5.0 roller motor

OK, so here's the deal. A long time ago I had a 5.0 roller motor out of a 2000 Mercury Mountaineer (Explorer) built for mama's 55 Ford custom that is on eternal backburner. It's basically bone stock but has a Trick Flow Stage one cam. Pretty tame.

Tonight, I started cleaning out the shop for our big move and ran across the lower and upper intake complete in my junk. I pulled it off because years ago there weren't a lot of options for the newer stand alone harnesses, but since the LS swap craze hit, the aftermarket wiring world blew up. They now make a complete harness for this engine setup. https://www.stinger-performance.com...es-8/mg-91E-4.6-5.0-explorer-harness-telorvek

I kept everything apparently. Looks super complete. My question is this: Is this a good system, reliability wise and if so, are there things I need to pay attention to. It looks like the majority of parts are still available. I plan on replacing everything to make sure we start off with a good baseline.

I just don't wanna spend money collecting new parts if this is a dud system. I am in the middle of building a house, so all I can do is collect parts and box them up for later.

I plan on using the serpentine system, the coil pack ignition setup etc. It's about the ugliest intake I have ever seen, but this is a hood down custom (as it should be) and I will detail it out to make it look presentable.

Anything I should know?

 

I have lots of info, too much to type in one setting. Here's the overview. What you have is EEC V ecu setup. It has a single feed fuel system. Most have changed to either eec iv which you can use a Painless harness but requires a distributor instead of coil packs or you can do what I have done. I used a 96 explorer wiring harness and ecu. It has the earlier dual line fuel system. 96 and 97 don't have anti-theft, later versions do. That is a gt40p cylinder head that not all headers will allow spark plug access. I have used several of these and been satisfied with the end result. Most everyone I have torn down has had very little cylinder wear. Berry hone and install rings, bearings, oil pump, chain and gears and if you want it to rev at all, install a Trickflow valve spring kit which should have been done when the cam was installed. One of the engines I did I used LS behive springs and retainers. With a stock cam that worked very well.

 

The Explorer 5.0 makes a nice driver engine in a lighter vehicle especially when you use the OD transmission, I’m sure there are other intake’s out there by now.
I guess I’m to cheap and lazy because I would use a 600 Holley , Edelbrock performer or performer air gap and a MSD stand alone distributor, performance will be equal or better fuel economy depends on the guy tuning the carb but if you’re driving less than 5k a year, two or three mpg shouldn’t matter much. I guess I’m a believer in the keep it simple stupid mindset.
