I hate to rain on your parade but this was never more than an over the counter dealer item. As mentioned in post #80; "has anybody ever seen one, a production 1962 383/343 vehicle?"
The fact that Mother Mopar made it legal & NHRA accepted it as fact is true. But they made about as many of these engines on an assembly line as they did the NASCAR single 4bbl Hemi!
