Anyone ever do this swap with the explorer GT40 upper and lower, I got a set and didnt know how tough it would be to do on a weekend..... I got them from a buddy of mine and would like to do the swap.

4 hours probably. get a real gt40 lower and save yourself a bunch of hassle.

p ports are small and no tap hole for temp sensor i think. if you dont have good heads or spraying more than 150... i wouldnt waste the time

It already has #5 tapped out for for the sensor, yeah i have the stock heads still too, I need to pick me up some..

pretty easy swap then. souldnt take more than a few hours to do. you just need to plug like 2 of the vac ports in the upper that you dont use. other than that and the #5 runner its pretty straight forward. just make sure you install the lower properly to avoid leaks

Which ports will I have to plug??

nacanitihs

um which ever ones you dont use lol. i mean the hoses are all diff sizes. i plugged the long metal tube one that comes out the front and annother one i cant remember... but you have 4 vac lines you need to hook up to the intake.

vac tree
pcv valve
fpr
charcoal canister


the frist 3 hook up to the back underside of the intake and the charcoal canister goes on the front underside (bent tube near the valvecover)

You can just set each intake side by side and swap everything and plug what you don't use. It also a good idea that you change the oil LAST. When you remove everything, coolant can go where you don't want it, so by changing the oil last, it will flush everthing out when you drain.

Also, do whatever you can afford while you have it apart, maybe some valve cover gaskets.
