Crossram Package
« on: May 17, 2018, 11:14:35 PM »
I had one of the very first crossram packages that GM sent to a few folks. I've seen several complete NOS setups for sale over the decades but I see subtle differences between mine and the later issue units. Of course, mine had the 1st design carburetors with accl pumps on the primaries only. One thing I definitely remember is the fact that there were NO manifold cover to manifold bolts included in the package. I suppose that's why folks are debating to this day about what the correct bolt head marking was supposed to be. There isn't a correct bolt. I remember using plain cheap hardware store bolts with no marking on the head, at all. Also, the throttle return spring bracket appeared to have been dipped in near gloss black paint. Brackets in later packages were natural, unpainted.
My new 2X4 package also included the extremely rare special fuel shield that was to be installed behind the left carburetor. (image below) (eventually sold to Wayne Guinn decades later) I think only a handful of 2X4 packages included the shield. Wayne posted a picture of my shield in his book, Camaro, Untold Secrets.
The package also included the four blueprint installation instruction drawings and parts list. I made copies of those sheets many years ago and my GF was selling the copies on ebay. I think several folks have made copies of my copies and still sell on ebay. I sold what must have been the 1st design cold air plenum about 20 years ago too.
 I still have a LOT of info from GM on the crossram.

I have no experience with these systems. What is the purpose of the shield behind second carb?  Welcome and thanks for sharing.

As I remember the story, someone in engineering decided that because the rear carburetor was dangerously close to the distributor, a fuel line leak and a spark would be disaster. Then, someone in the legal department decided that the shield was somewhat an admission of guilt so it was deleted. From what I understand, only a very few of the first 2X4 packages included the shield.
My original parts list that was included with the package does not show the shield.

I raced the car in NHRA D/MP class until about 1971. I then sold the car less engine in about 1972. The buyer installed a 358" small block and continued drag racing for a year or two. It then went to someone that stored for several years, then it disappeared. A friend of mine said he saw the car completely restored back to original at a car show about ten years ago but he didn't get the owners name. I ranm the VIN a few times but no results.

Michael,

I bought a set of those years ago on eBay, 1968 dated prints with the crossram plenum A/C setup clearly shown on the prints. I'm glad to have them, always wanted to find a set of '69 prints to verify what I had collected for my "cloned" crossrams I built over the years.
Always impractical for the street, but visually impressive to say the least.

Welcome to the CRG -

Regards,
Steve

Well maybe it will surface again. What became of the motor that you held onto?

Thanks Steve. Your copies are most likely copies from my originals. I think only very early 2X4 packages for 68 included the instruction sheets so there no new sheets for 69.

The 305" motor eventually went into a friends 64 Nova with Enderle injectors for street use. LOL. The crossram sold to a guy in southern Illinois for $250. minus the cold air setup.

I found a picture of the cold air plenum. I'm told this was a 1st design plenum but I don't know what the difference is.
