67 Z28 intake with '65 casting date
 

I have a '67 Z intake with a casting date of 12-65. It is identical to the Z intake with 2 exceptions: No firing order and it has an 0- engineering casting number signifying that it was a prototype Z28 part. This intake has never been restored or blasted and is in beautiful condition. Price is $1500. Frank Payne 402 393 5252

Hello. Is this like the one you had/have? I'm searching for as much info as I can on this intake, with very little success. https://www.yenko.net/attachments/use...er0u_60_57.jpg
I appreciate any help you might offer. Ken

If you ever come up with a Z28 tripower prototype with an O dash number and a Winters casting mark, I'd likely be interested. [img]<<GRAEMLIN_URL>>/smile.gif[/img]

----Isnt this simply a 1966 Corvette 327/350 intake???......Bill S

Re: 67 Z28 intake with '65 casting date
 

The 0- was experimental stuff.

Re: 67 Z28 intake with '65 casting date
 

No question it's experimental...no doubt it's not Z-28.

Re: 67 Z28 intake with '65 casting date
 

I have found info suggesting the very first Z prototypes had 283 short blocks, before the decision was made to combine the 4&quot; bore 327 block with the 3&quot; steel crank. I bought this immediately upon viewing it on ebay, because i remembered seeing it somewhere before in a magazine picture back in the late 70's to early 80's. It was in a press type GM picture, where all the 302 Z28 engine components were laid out nicely on a table, or other flat surface. It was a black &amp; white photo. I figure they used the L79 design, but &quot;smoothed&quot; the runner turns, and raised it up some more. I have yet to remove the bottom pan to see the date, but I expect it to be within the Z28 early development period. I need some solid proof. But, info about the Z28 program points to this being designed for that option package by winters.

Charley, you have one of these beauties right?

----First, I stand corrected. I know little about the genesis of the Z/28 program. Its great to learn about this stuff........Bill S

Yes I have one on my 67 Z with the aluminum engine. Cool to see another one. https://www.yenko.net/attachments/use...3-3354-008.jpg

Aluminum small block? As in all aluminum GM small block? Can you tell us the story on the motor please?

I paid $550 to my door WITHOUT HESITATION to own this baby!!! Maybe it makes up for the '67 427/435 Vette 3X2 intake I once had, that I sold at a NY swap meet in the 80's for under $200!! Sold it to pay for new driveshafts in my Vette motored '75 K5 Blazer. I snapped BOTH power braking for the amusement of my friends. I obtained it in trade, for a cast iron Saginaw 4 speed out of a 78 Malibu 4 door!!! Ohhhhh, the treasures I had that I let go of!! Lets not even talk about the '65 409 4 speed Impala SS CONVERTIBLE I took parts from in a Catskill's junkyard....to build a 6cyl rat!!! 7K tach and all... 20/20 Hindsight...

Re: 67 Z28 intake with '65 casting date
 

not to hijjack the topic, when I used to sell at Carlisle, I sold a &quot;complete&quot; NOS x-ram setup for 3500 bucks including carbs, fuel lines, and every part and also some duplicate/extra parts even the aircleaner and 2 foam seals (that were junk once we opened the boxes)... haha ... and I delivered it from Philadelphia to Chicago for that price !!!! I thought I killed on that deal !!! haha....

cool intake though..would love to have it, but my 67 Z project has other more urgent priorities right now.
Good luck with it. You need to find an all-aluminum motor....and then buy a 67 Z for it just like Charley did !!

Re: 67 Z28 intake with '65 casting date
 

I'm out of the Z28 game...since I had to let my Black '81 4 speed w/o AC, and my 30K mile, full option, black, orig. owner '86 TPI G92, 4 wheel disc brake IROC go. Now I'm just collecting Vette, and Z28 engine goodies to use on my '55 2 door sedan.

Re: 67 Z28 intake with '65 casting date
 

Very cool manifold and I'd like to have one... but it still has nothing to do with the Z-28 program though.

Re: 67 Z28 intake with '65 casting date
 

I disagree. It pre dates the Z28 &quot;production&quot; hi rise...and it is almost identical. It seems almost certain, to be one of the earliest prototypes leading to the Z28 assembly line version with casting number and firing order. It is definitely not a L-79 dual plane...that is obvious. And it has an &quot;0-&quot; experimental part number, so what other explanation makes sense?

Re: 67 Z28 intake with '65 casting date
 

Way I heard from friend who has one of the original 1967 Camaro Z28 test ones with the intage on it that were given to Nascar crews to do a test at Daytona all those cars came out before the 1967 ones ever hit the market. His had disk brakes all the way around still had the headers on the 302 original engine trans and rear no back seat painted orange under neath and when he took paint off had number on the door he still has the car don't know if they gave 20 or so of them to test out.

Re: 67 Z28 intake with '65 casting date
 

For arguments sake, let's say you're right. Then it proved inadequate and may have led to another 0 design that led to the tuned runner open plenum 610 manifold. There were thousands of experimental parts made back then to keep GM competitive. Your manifold could have been cast for any number of reasons or applications. It's a very cool piece of Chevy history, but saying it has to be a Z-28 prototype is probably not accurate. It is dated way before the conception of the Z, and VP stated that the engineers used off the shelf parts for the prototype Z. So the manifold was apparently not specific for the 302. But who knows, you could just as easily be right, but I doubt you'll ever be able to prove that.

Re: 67 Z28 intake with '65 casting date
 

Not trying to prove it. Not trying to sell it. But...I am pretty comfortable with the possibility that I just may have something special here. And besides...what other explanation is there? What other GM winters dual plane hi rise intake manifold looks just like it in almost every aspect? Why did this part become reality? For what purpose? The expense of casting it Had to be justified somehow. And the &quot;coincidence&quot; that the 1966 introduction of the very first Z cars...with their unique intake (different from the 69-72) corresponds to the date on these 0- manifolds, is enough for me. It just seems obvious. Maybe I'll never know...it's still badass!!

Re: 67 Z28 intake with '65 casting date
 

Anybody see any other 0- manifolds like this in that time frame with different configurations ?

Re: 67 Z28 intake with '65 casting date
 

I'll put my worthless 2 cents in here. The runner design tells alot here. Don't pay attention to the 3 hole opening. The runner design is very very close to a 610 intake manifold. The date comes in close to Z development. They did use off the shelf parts for the Z, however, the manifold wasn't there yet. There had to be a missing link between the 490 and the 610 manifold. I think this is it. Remember, in 1967 the 396 069 intake went to a 2 hole opening. In 66 it was still a 3 hole 069 manifold. I can see this 0-117 manifold being the prototype for the 610 based soley on runner design alone.

Re: 67 Z28 intake with '65 casting date
 

Matt, I agree completely. It could have also been experimental for other things but certainly many key points were used in the production z manifold.

Re: 67 Z28 intake with '65 casting date
 

I agree completely, the big block and L79 intakes moved away from the 3 hole carb flange around the same time. I don't think your two cents was worthless...thanks for the support. I am going to try and find that old GM press photo of the early Z28 engine components all laid out...because that is where I saw this intake as a teen in the early 80's. The search continues...and the mystery remains unsolved. Ken
