the 348 came out in 58 if I remember right, then the 409, then wasn't there a rare 427 version too??????????? as kid I remember people say the 409 wasn't worth a dime and the 348 was a junk, boat achor
JL could have made a sleeper limited edition here. JL could have made the exact number with 409 keys matching the amount of 64 impalas were really made with the 409 engine and the rest of the them 396 keys, and not told anybody about it
see epay Item number: 260021153293 for a nice pic of the JL and key

I saw a '65 2-door hardtop with a 409 CID a couple years ago at a show and shine.
I didn't know that they were uncommon. Or should I say that familiar OFAS word "rare".
I believe that Chevrolet made a 427 CID limited production engine in 1963 that was
coded Z-11. This is not the same 427 CID that was used in later years in most Chevy
products including Corvettes.
Yeah, your right. Almost forgot about the "Z-11" Impala 427. That was based on the 409 block. About 55 produced. The "Mystery Motor" 427 was, I believe, based on the Mark IV design. One of the more famous cars running this engine back in the day was the "Holly Farms" '63 Chevy. Junior Johnson, I think, was the driver?
unsure who the driver was, but if remember right the "Mystery Motor" was a cheater engine, chevies last ditch attempt for nascar at the time, thier answer to the hemi.............it failed at the beginning becuase they blew.
The mystery motor was run by Johnson in Nascar in 1963. It was stopped after that year because GM put a ban on factory racing. There were plans in the books to put the mystery motors in 63 fastback Novas for road racing of all things but that project was also canned. The ones that survived were all used in drag racing.
the story I was told was that in the first race the new 427's all blew apart before the end, GM big shots were embarrassed and quit nascar.................but who knows if that's true or not
Sort of, what happened is that yes, Junior's motor blew apart in it's debut at the end of the Daytona 500. He won 7 races after that with his mystery motored Impala. I am not really sure if anyone else was running those motors.
In 1963, GM decided to follow the 1957 Automobile Manufacturers Association ban on factory-supported racing. The Gran Sport Corvette was another car killed by the GM ban.
Ford and Chrysler told the AMA to go pound sand and continued their racing programs.

too weird,looks like a 63 Nova that was humped by a 66 Charger
