Back to 409 stuff........

Hey Rocky J. who posted the '64 409 pictures.....how "fast" did you get your 409-425 hp to go back in the day? Do you remember any mods you made and equipment used? Looks like a street/strip car, so maybe you didn't have a competition rear gear like a 4.88 or 5.13?? Thanks a lot, LOVE the "ol" stories!

Hi: my name is Rocky Jordache ,in case you don't know me. I am the founder of the
company 21tek -- at 21tek.com where you can read my about my auto experience.
The 64 supersport in the pic was equipped exactly like the beach boys song. My dual quad ,
4speed ,4:11 ,positraction 409. or something like that. Anyhow i had jetted the carbs up
curved the dist. and removed one of the two head gaskets that the 64 came with and
just put one new one back on. This really picked it up. I had lake pipe type cutouts that you
can see in the pic. And Mickey Thompson alum mags. very rare and expensive back in the day. I only raced that car twice at the strip both with only street tires. It only turned very low
13's as i recall because it would spin the tires and leave long black tire marks through
third gear. But man was it fun.The car i owned prior to the 64 was a 62 chevy SS convert.
with the 327 -300 horse engine. It also had a 4:11 gear ,but i worked at a SOHIO gas station
and had purchased some 8:00 series Caddy atlas Bucron soft rear tires .and that car would
also turn low 13's even though it was a much lower class. Something you young guys should know about the w engines. Once the got to about 5000 rpm you could not tell by the sound of the engine how high you were revving ,because the pitch of the engine sound barely changed .You could not tell if you were at 5000rpm or 7000, And many people blew their engines because of this. Those were the days.

Sorry for the late response but for 2009 I'm trying to use the computer LESS...too much to do around here! Those are pretty decent times for the '09 given the time period you ran it....the tires compared to TODAY and Track conditions then.....I've heard of the head gasket deal with the '09's before. Trying to find out what a 425hp would do "back in the day" WHEN prepped for class competition....I don't think too many ran that combo back then....409hp and 380hp seemed commonplace. Some guys have tried the 425 hp more RECENTLY as in the last 20 years or so....don't know if anybody was knockin on the 10's though....wonder how Aubrey's doing? Anybody here remember "Mousie Brown" back in the day? I think he held either A/S or B/S record for a while with a 409hp '62 Chev. post car? I GUESS I could bounce around on the 'Net to one of those 409 sites but consider the info here to be more accurate! BTW Rocky, does the process you mentioned on your 'site replace the earlier dry film coating process? Thanks!

Mousie Brown used to run a 1962 409/409 Impala Convertable A/S at Aquasco, Manassa Va., and Capitol when I was running my 65 Plymouth. He usually ran high 12,s and low 13's back in the early 60's. He was partnered with an "ANNABEL WALKER" (spel ?) with Brown & Walker on the quarter pannel. I believe SHE owned the car. In 1966 Mousie got a 66 427 Biscayne and later either a 66 or 67 396/375 HP Chevelle. Then came either a 68 or 69 396/375 Chev nova with a turbo 400.

No "old days" here in my shop, wannabe !
Dyno'd my engine a couple weeks ago ( 3rd build ). Looks like I FINALLY got the valve train stabilized, by using Comp's new tool steel retainers, and a set of heavy wall Manton pushrods.
Pretty darn happy with this engine now ! Spins the RPM that I always thought it should, horsepwer hanging in there.
According to the dyno numbers, which don't have a great peak, but a very respectable average... with a perfect operating chassis, the car weighing in at 3640 ( with me ), should run a high 10 @ around 121 at sea level.
Perfect chassis ?
HEEE HEEEE !!
don't know about THAT ? !

good engine though

Aubrey, keep us posted especially when you get to the track!

Greg and SS ; Just wanted to say , i revved my 409 to 6800 - 6900rpm with
stock springs shimmed .060 . A few times went way past 7000 accidently ,but never blew her up. They really rev fast after about 5500.

It's very possible that we all had a thing or two to learn about valve springs and cam lobe profiles.Stiffer doesn't always mean more rpms,but could produce a flat cam. The valve train dynos and engine diagnostic equipment didn't exist then that we have now. That definitely could have contributed to the tendancy to flatten out and nose over that these things were known for.Regardless of valve train equipment,what did you do about the 1000+gram piston weight and the short rods?
