Need Help! SBC Injection Intake Identification ???

Hi Everyone , on a recent Hemi parts search I came across this Chevy Small Block Cross Ram Injection set up. I can not find any info anywhere on this manifold after hours of searching I am still lost on who could have made this. There is no names are markings anywhere. There is a serial number that appears to be similar to GM casting numbers but I am not sure. I am a Hemi guy and I am a little lost when it comes to SBC's. Any info would be helpful.

 

Ok one person Pm'd that this might be a Marine set up. Just thought that my ring a bell with someone.

 

kind of looks like a variation on the GM cross ram injection manifold.

 

Whenver I see rough-cast but operable intakes with GM-type casting numbers I am put in mind of all the slick stuff that Smokey Yunick did for the performance dept under the cloak of research. This is a utilitarian-looking (not finished for sale) unit that could even have been fabricated for early Corvette racing cars (Gran Sport?). Merely supposition on my part, mostly because prototypes are typically unbranded and unpolished, as are competition-specific parts. Lot of stuff went out the side door of GM during the racing ban days....

Thanks guys for your input! RevKev6 I think you are right this does look like a variant of the setup you posted. When was that manifold produced? I have never seen one before.

Propwash I like your story side door Prototypes I appears to have ran at one time but with minimal use. I wonder who's project this was?

 

No throttle blades?

 

No Blades, I was thinking that maybe the runners on each side went went into into a larger plenum with some type of throttle body but I am only speculating.

 

the /00 part number looks like a GM prototype marking.
These were mainly used on Indy stock block engines. I think the lack of throttle blades or carb mounts indicates it was set up for a turbocharger with a single throttle valve farther upstream. Nozzle sizes would tell you if it was set up for Methanol or gas. Most likely Methanol for Indy cars. Some of these wound up in the hands of boat and circle track racers, but I haven't seen one like yours before. They have a restriction to flow where the runners cross each other and I don't think they flow as well as downdraft intakes. The runners are also "interlaced" which makes one runner go around the opposite one. You have one runner with a good port approach, the other is not-so-good. GM also made an intake with the runners parallel to each other that has a better shot at the port. That one was used in the Grand Sport Corvettes in both weber carb side draft, and injection versions.

My intake has the same casting number.

 

Thanks Dave ! You definitely know your stuff!

 

I wonder what car this was built for? Anyone have any pictures of Stock Block Indy engines from the early to mid 60's ?

 

Here are a couple pics of the weber version. I believe the one with injection was designed for turbo applications, as someone already stated. I'm trying to find pics, but the one I saw was on a cosworth indy motor. I'll post them if I can find them.

 

I dont even like SBC's, but that thing is WICKED!

 

I have only been able to find pictures of the Cosworth Indy Cars as well ,those are some nice manifolds you posted pictures of I think they are Moon's. This one is a Factory GM manifold. Thanks again for looking for pictures!

 

I am with you on that one, I am not really a SBC guy either but this one makes me drool !!!

 

Mr. Zora Duntov ,rip, would have the answer. I can't help much on the identification but would like to comment on its uniqueness , it would certainly be cool in a Chevy museum on a replica engine it was used on. Perhaps someone has a picture to post as the thread moves on its course. Hope to see some more history on it. I wonder what it is valued at?

 

Here is the Corvette Grand Sport intake. I like this one much better. These ran Webers, 58mm side drafts, or fuel injection bodies were added like this one. The runners are much better, more equal length, less curves. This intake looks a lot like the base for the late 80's Tuned Port Injection. The throttle bodies appear to be Hilborn, but they don't say hilborn, just some numbers.

Not to hijack or anything But, David Pozzi Is a member now! Glad to have you with us
you should do an introduction for the guys that may not know who you are

 

I did find some info that these started out when the CERV I and later CERV II cars were built. GM planed on using them in the GS corvettes. Have not found pics of the injection one on an engine yet, but I'll keep looking through my stuff.....

Some of the articles I've found, these things were also used on some formula 1 engines, even some other road race cars that had small cubic inch engine rules. They wanted to go with the cross ram or "lay down" desing so they could be kept under the body and not stick up like the typical hilborn/kinsler injections did. There were a couple of 4liter and smaller V8's that chevrolet built for testing in the CERV that made HUGE hp numbers and spun some serious rpm's!!! Cool stuff, kind of fun reading about it again.

 

I saw the CERV at Monterey Historics a few years ago. I think it's owned by Mid-America now. Also I think they purchased the rear engined GM prototype (corvette?) or whatever it was. Smokey says in his book he cut it into 4 pieces but someone put it back together.


Mike,
Where do I do the intro? Here or is there a section for that?
I'll look around.

Here's my new guy introduction: http://www.jalopyjournal.com/forum/showthread.php?p=4871489#post4871489

 

Here is a Grand Sport page showing the last intake I posted with parallel ports being used in 1963.

Hey everyone thanks for all the info , I am fairly new to the Hamb but I have always been impressed with how helpful and knowledgeable this community is.

I have had some new updates as to the more possible history of this manifold. I spoke with a some one who today who said this manifold is the earlier version of the ones found on the Grand Sports. He mentioned these were the first prototypes and that they experimented with fuel injection on a few motors one of which was a Hemi Headed twin spark plugged 377ci Aluminum Chevy. The motor was never used but it did run. I am a Hemi guy so this was great news to me !

I also had time this morning to put together a mock up of what this engine might have looked like and I will post pictures of it tomorrow.
Thanks again for all your help and big thank you to David for becoming a member to help out a fellow enthusiast.

 

Well I don't have a lot of Chevy stuff but I was able to put this mock up engine together using some stuff I had lying around. Its a 1964 327 and some late model alum heads. The original block would have been made of Aluminum so I painted this one as such.

 

There always seems to be confusion on the SBC Crossram set up. This setup was designed by Giotto Bizzarrini while working for the Iso Rivolta company. He is the same man who designed the Ferrari GTO and the Lamborghini V12 engine, so it makes sense that sense that he designed the beautiful Crossram set up . The first manifolds were hand welded and incorporated a gear drive mechanism to control the four side draft Weber carbs. A lot of linkage systems have been tried over the years with cross ram set-ups, but Bizzarrini's is still by far the best. It allows you to individually tune each carb without affecting the linkage connecting the other carbs.

 

As the design evolved it was cast in magnesium and aluminum at the Campagnolo factory in Italy, Bizzarrini also designed a Magnesium oil pan, brake calipers and large 10" wide rims.

Bizzarrini started his own company after leaving Iso Rivolta and used the crossram set up on his street and race cars

 

View attachment 3186651 Although rare there are still units being made today. many of the aftermarket units are cast incorrectly and although the manifolds are cheap they often require a lot of rework to make them usable. Giotto Bizzarrini is still alive today in Livono Italy.
