Mark,
Perhaps you should go back and at least see if the 380 air cleaner got saved. They're impossible to find.
I've documented many legit '62 409 blocks and believe it or not, about half of them are QAs. But today it's very rare to find a restored 380 car. It seems like today's hobby dictates that a 409 HAS to have 2x4s to get any respect. It's funny, but I guess it was the same way back then. The owner's father (who bought the car for him) wouldn't allow him to get the 2x4s and he got teased a lot that he didn't really have a 409 - he had a 380! So, without his father knowing, he took it to a different dealer in So. Jersey for the conversion.
