Crossram manifold

Here's the CARS magazine feature on their Z-30 "Green Meanie" street/drag racer that was their answer to the
"Blue Maxi" project Camaro done by Car & Driver magazine.

I remember the blue maxi, as I have that magazine somewhere in my collection, but I don't recall the 'green meanie'..  Do you have any color photos? 

[Jon Mello]

Sorry Gary, no I don't have any color shots of the car. I wish I did but it I don't think any ever made it into print. I would deduce that the car was fathom green.

Any shots of the side of the car I'd like to see what those side exhausts look like on the car.

[Jon Mello]

Sorry, Todd.  Those are the only shots of the car that I know about.

Many thanks to Frank Dihartce for sharing pictures of his April 8, 1968 dated crossram with us. Frank tells me that
he believes this is the earliest casting date that was made available through the Chevy parts department for purchase
by the general public. These April manifolds still had the provision for the oil shield on the underside on the bottom
half of the manifold. Frank's manifold is using the LIST-4295 carburetors but I think GM was still using the LIST-4210A
carburetors in April '68.

More awesome crossram goodies from the Frank Dihartce Collection. Some neat details in these photos.

Here's a November '68 crossram manifold setup, also from the Frank Dihartce Collection.

These are some nice, close-up shots of an original GM fuel block for the crossram set-up, again from the Frank Dihartce Collection.
Many thanks to Frank for sharing these photos with us.

Here's another crossram from the Frank Dihartce Collection. This is what Frank has to say about it...

"This is another crossram 4.8.68 dated setup I bought. It is stamped “KL RACING” on the front runner, and came with two 4295 Holley carbs 891 dated, fuel block with four lines and one hose nipple, oil splash shield, oil fill tube, and water neck. The manifold lid has no date which is consistent with the other 4.8.68 unit I had, and the manifold bottom is exactly the same as my other 4.8.68 unit."

Anyone out there have any thoughts on who KL Racing might be?

Fascinating and informative thread! Were teams allowed to run either the Offenhauser or Edelbrock intakes in period, or was it only the GM product that was homologated for use?

[Jon Mello]

Thanks, Steve. You could run aftermarket manifolds starting in 1971 but by then the 2x4 manifolds had been disallowed. Camaros were only able to use the GM crossram in '68 and '69 then they had to go to the single 4-bbl manifold in 1970.

Thanks Jon, great info! So given the prices commanded for the GM manifolds, and their scarcity (as I say that there appear to be two of them on ebay as I write this), are HTA car owners running 1968/69 cars allowed to fit either the Offenhauser or Edelbrock intakes or can they only fit the GM intake, as per the period?
