The engine that went into "production" was a SOHC, meaning it had a single cam in each head. Not sure if you or others think in terms of there being two cams on the engine meaning it's a dual overhead cam. Normally that is in reference to the number of cams per head.

Now, as to the senile thing, we'll need to keep an eye on you to determine that. One good thing though, when you're senile, you meet new people every day...............and they already know your name!
