IMHO, excessive engine weight wasn't the reason the 409 was not available in the 62, 63 and 64 corvette. The 409 weighs about the same as a 427 at around 650 lbs. Chevy had just come out with several variations of their new 327 and at a top rated 375 hp was just 5 hp less then the single four 409, which was rated at 380 hp. Maybe John Z could give us the definitive answer. I've always wondered about this....

Mike you have a better memory than I. I vaguely remember that to be the case back in the day, but have slept since then. Good catch.

There is a guy around Cincinnati who has a black 62 Chevy with a 409 bus engine and a strange washing machine motor alternator.
He might know why they were not used on Corvettes.
Can you post some pictures???

I'd question the return on investment it would take to put that low volume engine in a low volume car for starters. What's the payback?

The second thing I'd question would be whether there'd be any gain in performace as relating to a "sports car"?

Your run of the mill, factory stock engines were not that steller of a performer. They did make a lot of noise though when the throttle was opened.

Yes, I know some professionally prepared 409's were very, very quick.

Might have been the 105 amp Delcotron that was used in police and emergency vehicles. Not positive here but I believe they were available from early 60 to the early 70's.

That's the one he has on his 62 409 black rag top.
We like to give him grief about it.
The owner is a member of this forum, I hope he chimes in......

I can give you the answer. If you read Ludvigsen's book on the Corvette, he indicated that Duntov was never a fan of the "W" engine in the Corvette. The C2 was already a heavy car and the handling dynamics weren't too great with the SB motor let alone the BB. I suspect that the horsepower wars contributed to the introduction of the BB--not anything that Duntov wanted. What you saw in the GS is probably what Zora always wanted, assuming he could have homologated it.

The Cobras did all there winning with a light SB engine and never won an international event with a 427. As a practical matter, they never sponsored a Factory 427--period. Unlike its predictable 289 brethren, the 427 Cobra was a pig to drive.

Hey guys I love the 409 discussion. I am putting one in my 64 and have a thread on it here. I'm not sure how to put the link up but tomorrow I will post some pics of the motor I'm just about to drop it in the car for mockup. I'd love to see some pics of 409's in vettes if any one has any.

And how about an all aluminum 409, built into a 509. This is one my machinist recently built for a customer. Should weigh close to the same as a SB.

We have here what distresses me about some of the writer's knowledge (or better, LACK of knowledge).
Roger above posted a link to the history of Chevy big blocks ( http://en.wikipedia.org/wiki/Chevrolet_Big-Block_engine ). When you go to the link, then scroll down to the Z11 section, DO NOT take the information as gospel, because some of it is totally incorrect! First, the writer states that the 427 Z11 engines were all aluminum. WRONG! The were cast iron just the same as any other 409 engine. Only the 3-piece intake was alum (this is well documented from Chevy records). What is NOT sufficiently documented is the actual number of Z11 cars that were built. Yes, it APPEARS that 50 whole Z11 engines were built, but it is NOT well documented that all 50 engines were installed in cars. Thus, the actual number of Z11 cars may be less than 50.
Oh ya, and the quoted stroke (3.95) is wrong---------------it was 3.65. The only other alum parts on those cars was the forward sheet metal/bumpers.
So, you can't always believe what you hear, and only half of what you see.
The bad thing about this is that when this kind of information is printed for all the world to see/read, and then when someone reads it, they take it as gospel and it just continues to perpetuate itself. I just hate it when these writers don't do their homework and get the facts straight.

That's a pet peeve I've had for MANY years Tom. Statements like "409" wheels", "truck motor" and "57 total Z-11s" continue to find themselves in print.
Too many magazine writers today are just out of puberty and their research consists of reading what was already printed in other magazines.

Default Ken Kayers Big Block books.

Ken Kayser is in the process of writing a book (s) on Chevrolet big block engines. I'm not sure if it will include the "W" engines or begins with the 396 porcupine head big blocks.
But it should be interesting
