Technical Hot 409s: Who has them or has built them in the past?

Sorry but nothing like a 409 in a 55!!!! The 409 i run in my 62 Biscayne I dump the clutch at 5300rpm shift at 6900RMP and go through the traps at 7200 RPM all good, also building another 409 for my 61 Biscayne and hope to be close to 800HP and run 8000 PRM with a original 409 block

 

Damn, if I win the lotto, I will buy one of those, drop it into a wicked 55 Chevy and go hunting for a piss yellow, puke green deuce coupe

 

"We build our own engines." -and yep 348s and 409s are GREAT street or strip engines. Crate engines are pretty boring.

 

I saw those. Wish I hadn't.

 

That's not the point. The point is you COULD go that fast on the street.

I'd be happy with a 500hp W motor. Beyond that, I'm into the chassis for a bunch of money to strengthen it up. I already need a new rear and would like a new trans.

 

500hp 409 very doable for under $10,000 with the right builder That's what i first started with, and and i have some stroker piston& rods and cam for sale from that same motor was 515HP

 

Some of the new heart

 

In 1966 my Fiat had an Algon injected 409. Not sure on the details of the engine. I am going to ask Jerry Adams, who built the car, some details on it. He said he sold the engine to a guy in Texas that just had to have the engine and he then built a Mondello prepped 427 the winter if 66

I just got this info today 6/17/13:

here is what I can remember about the 409, 10.40 et, 140-145mph. Engine was sold to a racer in Texas, never heard from him again. I think it had an Isky cam, Venolia pistons, heads were ported, home made hedders, that is about all I can remember, much of the machine work was done by Mick’s Auto in Racine. Hope that helps.

 

Puttin one in my 40 Ford standard coupe.

 

Bump.....

 

You can get the same look and most of the performance from a 348. Most of us over build for the street anyway. Modern, lighter parts will ease worries about over -revving.Most of the motors that blew back in the day were caused by the lack of technology for valve spring material.

I always use lighter, 11/32 valves in my new heads.

 

Those are some pretty puny looking valve springs.

 

Here you will see as much of a piston and compression you can put in 409 block

 

I built one for a buddy with the 427 crank in a 409 truck block ross pistons big heads runs real strong. Took a lot of work and attention to detail. Think the pistons were in the 800.00 dollar range and had to machine them. In the end I think it was worth it.
Engine went in a 62 SS 4 speed car has been lots of fun and many miles of happy motoring.

 

This was great to see

 

Gorgeous!

^^^^^And rare, especially in a FED!

 

We could only get 782hp out this one for my 61 Biscayne

 

anybody ever heard of lamar walden......

 

One DMF

 

Someone asked "Where do we go from here" ? A racer in Canada just got one of the new Bob Walla aluminum 409 engines running and made 863HP on the dyno.



Here is the link to the 348-409 site where they discuss this engine from the beginning.

They've come a long way from being "an old truck motor or boat anchor" to this.

check out my thread "street racing in boston in the 60s" my dad ran a sick 55, 409

 

Very cool guys. If I could figure out how to post a pic off of my phone I would show you the injection intake I just had made for my Project 60. Maybe after the ProCharger is installed.

 

I guess the point of building a "409" and then doing everything you can think of to make it not look like one is lost on me.

 

Nice engine! Go for it! Guys blew them up years ago because they were accustomed to buzzing a small block, and you DON'T BUZZ a big block including a 348 or 409, at least not for long!

 

Real fine...

 

Been buzzing this one for over two years 7200 rpm and she has well over 138 runs and still running strong

 

The big killer of W motors was piston weight. Back in the 60s A customer brought in a set of Jahns that weighed 1100 grams. New tech should get that down under 700 grams

 

Yep, with 3.25 stroke (same as 327) for the 348 and 3.50 stroke (basically same as 350) it sure wasn't unmanagable piston speed that blew them up at higher RPMs.

And I'll agree that the technology is there to make them live now days.
