The Class Cs never had the "real" Triton engine. The cramped engine bay meant they all got the 2 valve head lower powered V10. Not a desirable motor power wise. So bulletproof and long lasting (300K+ miles) most vehicles with them go to the junkyard with a perfectly good engine ruining the motor's resale value. Easy visual check: 2 valve, plastic valve cover, 3 valve, aluminum cover.
The three valve variant was introduced in 2005, so before that year all vehicles--not just the E series chassis--had the two valve version. To my mind both versions are real Triton engines (and so Ford calls both versions).
They're good dependable engines, as you say, but quite common and so not valuable in terms of money.
