Technical Hello to all and help required to id Chevy 327 intake manifold

IF there are ribs in the lifter valley, that looks like a CB Performance intake. I had a CB intake for Dellorto's, where the carb bases bolted to the valley as well.

 

That Winters logo is (one of) the defining features, to my knowledge no aftermarket manifolds will have that "snowflake".

 

POST #2 "hands down the politest post this month.....let's see how many min's til the winner! "
If my math is correct stumpy is correct at the 51 min. mark!

 

If you look closely the center has been milled flat taking off the casting numbers and its also milled under the breather which bolts down but seems to be missing a top. Sure looks like it's for Webers or some such carbs. Orner Automotive used these manifolds for custom injection systems also when you could still buy them separately from Chevy

 

Here's one I had stashed in my files....
Looks like a 1969 Chevy 302 motor with a lower Corvette F. I. intake.....

 

Can't ask for a better combo^^^^^......

 

A neat piece for sure. I love some different intakes from the norm.

 

Apologies for going off on a tangent - I've been looking at a dual Winters 4-barrel Chev manifold, no carbs (all eight inlets equal diameters). Are these pretty common, and should cost no more than any similar aftermarket swap-meet manifold? What years were these used, or offered as an option? Thanks!

This aluminum 2x4 intake (Casting #-
3739653), used on 283s in ’57 to ’61 Vettes
and p***enger cars, helped generate 245 or
270 horsepower with two Carter carbs.

Some examples with prices all over the board.

If the intake has 8 separate holes, it is likely a 1956 intake. The '57-'61 had two holes connect for each carb. There are two different versions of the '56 intake. Both are more valuable than the more common '57-'61 piece. Check the casting number.

 

Hello All, apologies for the delay in replying on my original post. You guys (and possibly gals) have blown me away with your knowledge and your generosity and speed in sharing it. You caught me quite on the hop! I think "mgtstumpy" has hit it on the head. please see below further photos of the manifold taken apart. As you will see the word "milled" is stamped into the top along with the depths involved. You can also see the tooling witness marks in the centre and around the area where the breather is attached and the machining goes right through the top while retaining the webs underneath. I don't know whether you can see, but each separate carburettor intake is number stamped to match up with a corresponding number stamped on the base plate. Underneath you can also see what looks like a date (15th Nov. 1963?) and initials(EJ?) cast into the base plate.
By way of context, this manifold came with a 1964/5 Merlyn Mk8 Chevrolet "Big Banger" Sports Racing Car that I bought in Auburn back at the end of August. This is one of only two built by Colchester Racing Developments in the UK, prior to being shipped to the US for racing in Can-Am and then Group 6 Sports Car Racing. It's had two owners in the US from new and has now come home (which I do feel bad about, as it's been so used to sunshine!).
If anyone can add anything further to this thread, either regarding the origins of the manifold, or indeed the car, then I would absolutely love to hear from you.
A very merry Christmas to you all!

 

Guess I goofed....
..... And I thought it was a factory "fuelie" lower intake.....

 

That' pretty damn cool, now don't tell us that you found it at a garage sale... or in the thread about the coolest thing you found; cheap! Thank you for the education and info.

 

The folks we meet here...Incredible!

 

Can you tell us what transaxle is in the car? Freakin' awesome, indeed!

 

The transaxle is a Huffaker BMCD, with a Halibrand "quick-change" rear end (so I have been told, but we haven't cracked open the casing yet). I believe these transaxles used T10 Gears and either a Jeep or Ford Truck Crown Wheel and Pinion. As far as my research goes, Huffaker made roughly 50 of these units starting in 1963, which were run in Genie, Cooper and other period Sports Racers using the Chevrolet 327 unit.
It wasn't a garage sale, as you put it Big Deuce, but actually in an auction with RM Sotherby's. Unfortunately (as it turned out for the seller), it was in completely the wrong sort of auction, as it was more of a vintage car sort of auction (1930's stuff in the main), so this odd black car in the corner, dusty and on flat and rock hard Hoosiers, wasn't really all that appealing for that sort of crowd. As a result, I bought it for $25k (which with shipping back to the UK came to around £25k) and I cannot see any other "Big Banger" Sports Racing Cars for less than £100k, so I'm kinda thinking I got a deal! I was even more pleased when the latest edition of Vintage Motorsport dropped through my letterbox and said the same thing in their auction review article. These cars are out there....you just have to keep looking!

 

Very cool, and priced well If you don't mind me asking, what are your plans for the car?

 

For what you paid, I'd say you've pretty much evened the score for the Boston Tea Party! I wasn't aware that CRD made "big" cars. Is that a tube-framed car? (I'm familiar with the Mk6 sports/racers, and I have a Mk3 Formula Junior.) Hope you can send more photos in the future, or provide a link if you intend to put pictures on some website.

 

I was wondering about the pictures in a previous response, which had balancing (?) slots between two diagonally opposite ports on the carburetor pad. The manifold I'm looking at does not, so apparently it's the earlier configuration. Thanks for clarifying that!

 

That is all just nifty as all get out. I'd say the car found it's right keeper too and it will return to the condition that it rolled out of the box originally in the future.

 

I had never heard of "Winters" speed equipment before. I've been following this thread for a week, and finally, as I was going to sleep last night, the connection between "Winters" and "Snowflake" just dawned on me! I guess age slows down the brain!

 

Yes it is a Winter's intake. The carbs that boilt to it should be Delorto or Webbers, given the era they would have been WCOE Webbers if I am not mistaken. Ol Dad ****** would have said that the Delortos were better carbs. The WCOEs were real finicky, they did not like changes in al***ude or humidity.

The intake would have been used in CanAm or PanAm racing. Unleess I am seriously mistaken (which I am on occaision).

You may not have to remove the heat shield to find the date code. Just roll it around real well and see what sort of other markings are here and yes as @DDDenny mentioned that cast in breather is odd and the whole setup seems to be as cast and never finished which would have been done by countless hours of dremmel work at the hands of an induction man.

 

If I understood you correctly; you had not heard of "Winters Speed Equipment", that would be because they were not an aftermarket supplier like Edelbrock, Why-and, etc.
As far as I know the Winters foundry was THE source for Chevys' high performance aluminum castings throughout (at least) the 60's.

The Winters foundry was still casting GM stuff into the '70s. I am pretty sure that I have seen 3 bbl intakes with the snowflake on them.

 

Thanx for sharing The story! Fantastic car!!

 

Winters also cast intake manifolds for Holley.....

 

Dear All,
Just thought you may like to see the first firing of the SBC fitted in the Merlyn Mk8. Had the Rocker Covers off today and determined that the Heads are "3782461" and matching numbers (with date mark G195, which I believe is "G" September, "19" 19th and "5" for 1965). I believe these are called "Camel Hump" heads and were fitted to Fuelie motors, but I am sure you guys and gals will put me straight! Presumably these are therefore quite good with large valves. Anyway, you can view the first fire up in 22 years at
The bag tank (bladder) in the original aluminium fuel tank has completely perished as it was fitted in around 1989, so couldn't run it for long!
All the best and a Happy New Year to all!

 

Everything about your story on getting the car and that intake are very cool. For sure you need to get that intake back on the engine in the car! The 461 heads are the high perf heads from that era. So quite likely the heads that were on the engine when it was built. They were used on more than just the fuelie engines, and not really that rare.

 

Spotted this in a Sports Car Graphics magazine ...July 1967..

Al Bartz Engines in Van Nuys California built the SBC engines used in the M-6 series of Can-Am cars before 1968 ..in 68 M8A cars switched to the BBC engines....
