The "Yellow" (actually orange) injectors are 19# injectors. I run themn on my car.

Early 96-mid '97 V-8 Explorers/Mountaineers had standard GT-40 heads. If you're sure the heads are off a Cobra (that means you trust your source) the combustion chambers are already the correct size and the thermactor passages are there. If not, see my previous post.

No I purchased the heads from someone different.These were 2 separete purchases. I believe the heads I have are 8.8:1 compression which they may stay like that considering I will be supercharging. Or after doing some research, I'll find out how high I can safely go with compression and still be able to add boost. These heads will definitrly be ported and polished too.

ALL GT40 heads carry the F3ZE part number. The unmilled heads came on the '96-mid'97 Explorers and Mountaineers as well as the '93-'95 Lightning. '93-'95 Cobra heads carried 60.6 cc chambers because the factory milled them to get a 9:1 compression ratio.

No biggie. I was just a little concerned that the thermactor passages might not be there if you have to stay smog legal. It may be a dog until you decide to supercharge it. You'll just have to try it.

Do the "P" heads have the thermactor passages and what's the compression on them? Sorry not trying to steal your thread Matt. I'm trying to deside on Explorer heads/intake swap.

I'm pretty sure they do have those passages but not nearly anything like E7's. And I'm pretty sure compression is somewhere around 9.5:1-10:1 due to smaller combustion chambers.

No idea how to get them onto the site!
I can get em on the comp, but my knowledge ends there! hahaha. Someone said I have to get them hosted??? 
I dunno how to do all that! lol I already took the pics (11 of them) so all I need to do is put them on here.Matt

If the TB is off a 96, it will have the hose connection that goes to the oil filler neck like the stock TB, if it is a 97 it will not and you have to take the one off the stock TB, drill the new TB and put it in. In any case you have to take the throttle crank (has the throttle ball connector on it) off your stock one and put it on the new TB or fab up a new one. You can weld it on, or use expoy with tech screws. You can use the TPS from either TB just the way they are - I'm using a 97 TPS on my car.

Killer score man. youll be hard pressed to find a better bang for the buck combo. Good idea to keep the lower compression ratio and crank the boost. That way when......er I mean, IF you pop a HG you will have some room for cleanup milling.
