409?




He might know why they were not used on Corvettes.
Can you post some pictures???

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.

We like to give him grief about it.
The owner is a member of this forum, I hope he chimes in......





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.











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.

Too many magazine writers today are just out of puberty and their research consists of reading what was already printed in other magazines.

But it should be interesting
