as Mr. F stated the other FE's did have thermactor as did almost all 68 stick shift fords with any engine size. but your real mistake is asking why hinder the 428.
actually a thermactor is to allow the engine to remain unhindered. the thermactor system does not rob horsepower to any degree. it, like the PCV, is a beneficial smog system as it requires so little power to operate and does not affect the way an engine runs.
the thermactor is a low volume air pump that just pumps cool air into the exhaust at its hotest point allowing unburned gasses to continue to burn after they leave the cylinder. the only figures i have seen are from a dyno test and they showed that at 5000 rpm a thermactor pump used between 3 and 4 horsepower.
considering the little power needed to run one and the fact that they reduce emission considerably they were used to allow the motor to be "hotter" than would otherwise be allowed. all in all it is kind of foolish to remove a thermactor system considering the benefits and low cost power wise.
