jwzg said:Are those GT40 heads off the Mountaineer as well? If so, you may need to have them milled to get to the stock 9:1 compression. You may want to go higher. I also believe that the early GT40 heads on the Mountaineer/Explorer didn't have thermactor passages drilled. You'll need to consider that if you are trying to stay smog legal.

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

jwzg said: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.

jwzg said: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.

Mattys5Oh said:TMOSS, What is the minor work needed to convert the TB so it can be used on a Stang.
Matt
tmoss said: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.
Mattys5Oh said:I can send you the pics if you'd like to see it. Just give me an e-mail to send it to.
