Technical Winters Small Block 1966 Intake Manifold.

Seen this Cool Chevy Tri-power with Holley Carbs for a Small Block, the intake manifold is by Winters, I can not find any information about it, was this a SHP Intake Manifold for the 327 or 302? casting date is 2-9-65 or 66
Casting # 3896927 or 3696927 any one have information on this Intake Manifold.

It's probably the closest you'll ever come to seeing a Unicorn.

 

Buy it at any cost! Hell, let me know where and I’ll buy it!

 

That sure is interesting, what a great looking Winters Tri-power Intake Manifold for the Small Block SHP 1967 350 engine.
That's what dreams are made of right there.
It would've been something if GM had introduced the 1967 Camaro with the L70 350 360 SHP engine instead of the 302 360 SHP engine back in 1966.
Thank You DDDenny Way COOL...

Big Bucks $$$$...
If the price is right then @badshifter may sell that Small Block Chevy L70 Winter's Tri-power 3X2 bbl Holley Carb Intake Manifold, MAYBE ??

So the 1st & 3rd Holley Carbs have Vacuum Pods is that how they worked? The 2nd (middle) Holley was the main Holley Carb that was used for starting bcuz of the Choke?
What is the CFM of the Holley 2 bbl carbs on this Tri-power?

Too bad the aftermarket didn’t pick up on that and offer a similar manifold. Although it looks counterintuitive, like a set of Rochesters on a small block Ford, it sure fills the top of a small block Chevy with carburetors.

 

Yes, the center is the 'primary' the outers are 'secondary'. I come from a Mopar background, but Chevy also did this on the big blocks. Probably lots of info out there on how they work, what the numbers are and such.
Remember, CFM is calculated differently depending on how many barrels (venturi) are being pulled thru.

Carbking knows his stuff, he's the only one that has a REAL Complete Holley Carb Kit for my 1966 780 Holley.
Bcuz the thread is older the first extra thread is not available now, wish there was a way to save the HAMB older information or retrieve the older threads somehow, a lot of excellent Car & Engine & everything else History is being lost one day at a time.
Thank you for the Holley Carb CFM information.

I would be very interested to know the list numbers of the carburetors.

Thanks in advance.

How about this one Bob.
I think I would come up with a different filter/top setup though.

Not Holleys, but should be fun!

 

This part of the History of the L70 information from DDDenny may have listed the 3 2bbl Holley Carb List Number's but it only shows referral numbers no other information on those part's. Sure would be great to know right.

Nice, its a much taller Intake Manifold, that pyramid shaped GM Tri-power Air Filter Top & Bottom like the L70 & the Tri-power 427 had is a Cool looking Air Filter Top & Bottom, does the Aftermarket make one like GM's ?

@DDDenny and others let's take a look at that kit.
The part number for the whole thing is discontinued.
https://www.holley.com/products/discontinued_product/parts/300-521
instruction sheet.
https://static.summitracing.com/global/images/instructions/hly-300-521.pdf

Under the Not Available kit, they have "We Suggest" the following:
Weiand 3x2 Dual Plane Intake- Chevy Small Block V8
Part # 7550 $749.95 (was $382 10 years ago)
Fuel Line Kit - 3X2 Carb set-up
Part # 34-51 $217.95 (was $110 10 years ago)
Carburetor Linkage for 3X2 Carb set-up
Part # 20-42 $274.95 (was $150 10 years ago)
Holley website does NOT show the carbs used in this system. You have to search for part #.
Center Part # 0-80683-1 REPLACED BY 0-80683-2 (N/A)
Outers 0-80684-1 REPLACED BY 0-80684-2 (N/A)
Yep, Holley no longer makes the carbs.
I didn't bother with the filters.

 

And I thought I had too much time on my hands!

 

Hey, I opened your link and thought, cool.
Then I scrolled to the bottom and saw they had all the parts and pricing. 2 grand. Too rich for me.
Then saw it was 2015. Uh oh, I thought, how much is it now?
Cue a search and the dawning realization that Holley, the company (IMHO) known for carbs but who has become a conglomerate run like a VC will still sell you the intake, the linkage, the fuel lines, the air cleaners but NOT THE CARBS! So I had to write it all out with part #s.
Yep, a big waste of time.
Hopefully someone else who might be interested will not waste their time trying to find one for sale.

 

Bob
Disregard my post per your request about aftermarket tri power, apparently I didn't delve into it deep enough, Holley setup is NLA.
SORRY

 

@DDDenny I was NOT calling you out at all! Please accept my apologies if you thought that.
No I am sorry it's not available, even if it would have been out of my own budget.

BTW, the 3 air horn gaskets are 85 bucks! I gotta play in the used or DIY section even for gaskets!

There is a HAMB member that assembles then sells the Offenhauser, Edelbrock and a few other older Tri-power Intake Manifolds with the Rochester, Holley (and those older two bbl carbs 94?) Carburetors, he does all the plumbing and linkage, ready to run & have fun. Are all the accessories made by him or does he have a big supply of NOS part's. $1500-$2000+ in the parts for sale. I believe he has a few up for sale now. They look great.

Air horn gaskets from other sources are much more reasonable!

I looked to see if the 340 carbs were still common new. Seems the answer is no...
https://www.jegs.com/i/Holley/510/0-4792/10002/-1

 

A single Holley Carb with your choice of many different Intake Manifolds sounds better after reading the part's list you looked up.
Tri-power's have that COOL LOOK just like Dual 4 bbls do $$$$.

@1Nimrod I think I'd trust a small vendor that builds a setup like you mentioned more than a huge company selling off the shelf stuff that may not have OE support after the sale.
I agree that a multi carb setup has the looks, and the Hot Rod article Denny posted showed it developed a bit less top end but had more 'under the curve' torque, exactly what you want on the street.

 

I agree, I'd buy from a HAMB member first, he makes some mighty fine looking Tri-power setups.
OLD REK $1500 for his Tri-power Edelbrock & Holley 94 Carb setup.
He can build whatever you need.

Also HAMB member fordomatic has this sweet looking Ford FE 406 Tri-power setup 390 1961-64 $1400.
To bad this wasn't for a Small Block Chevy.

Dustin

And HAMB Member hotrodhoodlum has a Tri-power for a Chevy Small Block $675.
Why Cool.

Everything is cool guys, I just wasn't paying attention, sorry.
