The car in question is a 88 5.0. I bought my car with GT40 heads. The smog pump is still hooked up to the belt so it runs when the car runs, but none of the connections from the smog pump are hooked up. So it is just pumping air out. I have most of the connections that it is missing from a conv. we parted out, but I am not sure if it is able to hook up to the back of the passenger side GT40 head... does any one know? what should I do? I would get rid of the smog pump but i live in california and need it for smog...thanks

The connections for the crossover tube (air to the back of BOTH heads) should be there. The heads were used on the 92-95 Cobras which had the smog pumps/crossover from the factory.

if they are explorer heads, it won't be drilled for them. However, even my gt40p heads from a 97 explorer already had the holes to bolt up the equipment, it may not be "functional" though with drilling the heads. Keep in mind, that the air is diverted to the exhaust once the engine warms up, and you don't smog an engine cold. for this reason, I'm just bolting the stuff up to make it look legit.

There were no smog ports in the back of my friends GT40's.

Just run the airhose down to air injection crossover tube in front of the cats. Does the same thing as the original system minus some relatively unnecessary switching.

W/ gt40P's, I see where I have holes drilled with caps in between - is this where I could bolt up the air tubes? Would I have to remove the caps or could I leave them in there?
Is this the same thing as the EGR?
