Hey Greg.... this is the site:

Yes, I have a 62 409 HP BelAir hardtop, setup for C/D Stock.
Looks like I'll FINALLY have a season this year !
Anyhow
Lots of new stuff for these engines now. Lamar has had a Z11 style head available for 15+ years, as well as a very nice ( expensive ) single plane 2X4 manifold. Bob Walla had his aluminum heads out 2 years ago... and Edelbrock introduced theirs last year. Edelbrock also has a dual plane 2X4 intake for small and large port heads, and they JUST introduced a modern Performer single 4 BBL ( about bloody time ! ).
Personally, I'm invloved in these engines pretty heavily. Last year, I designed and drafted up a single plane "air gap", single 4BBL intake manifold. Been working with the pattern maker for the past few months, and should have a casting shortly. Will finalize using a test engine on the dyno, and the manifold should be available within about 6 weeks.
Bob Walla should have an aluminum block available by summer.
So, if you're into a W Chevrolet...( and you have fairly deep pockets ! ), you should be able to build a proper 409, with a full compliment of modern technology !
