Brian....I noticed this statement too from the onset (in my own manuals), stated it in my first post, and basically drew the same conclusion. But, because some here remain fairly certain to the contrary, I have attempted to ascertain an answer from them to prove otherwise, by first having them check their cars or others for signs of the air injection heads (a key and necessary feature of the system), which would also be the most difficult part in removing any trace of the system. Because there were some earlier cars that had thermactor systems without converters, (and I still believe there may have been two different styles of injection systems putting air into the exhaust valves) I've willing to keep an open mind to the possibility of some cars at least having different equiptment than mine. But, either way, logic would dictate that any such system would still require a pump at the very least. I hoped the poster of the '78 system could post some pics of where his tubing attached...(heads or exhaust manifolds?) Since I don't have a complete listing of head casting numbers to prove that Ford actually made a 50 state 302 head between '75 and '78 that DIDN'T have this feature, I am willing to assume for now that they didn't. I'd further assume too from that, that any car WITH the air injection port heads also had the air pump and related equiptment, even though the heads can used without any problems if simply blocked off (like mine). So, unless Jon can come up with this kind of more conclusive evidence to prove against a thermactor sysytem wasn't installed on his car, it's my guess the judge would have a stronger case it did (by such a published source). Sorry Jon...I was trying to put the burden of proof on him, just on principle! If you are intent on being 100 percent correct/original in this regard, you'll surely need to continue the hunt for these other items. Getting them all NOS might be as difficult as a NOS white interior. I'd sugest taking way2fast's offer of a complete used setup, and going from there as necessary.
