I Have an original part numbered AM 4486228 68-69  STR-11 Crossram . I know it is original as I've been running it since the early 80's. Dennis might be able to ask someone , but I think I have a very early top
casting. No STR 11 cast into it by the front Edelbrock. Also on my intake see pic below, the area by the accelerator pump arm has no clearance cast into top for both carbs, as all the other intakes I've seen have . The bolt under the drivers side front float bowl is counter bored and not cast open like the newer ones.
I Don't think I've seen another top like mine.  Has anybody else ?
Also don't have the post count to post in the Ebay section , but the Canadian intake is also cracked by the driver side carb, rear inside stud.  I have a crack in the same spot.

I know that some of the early Group 19 parts, especially the ones that would be homolgamation parts for racing, did not have the manufacturer's name or part numbers on them. Apparently AMC thought that was important for homolgamation because of a mis-understanding of the rules. 

I hope that helps!

Dennis,
Yes, Look at the 1st picture under the accelerator pump.  it seems they added clearance for the arm of the accelerator pump and recessed it deeper for the bolt also on the driver side. Possibly to clear a 50 CC Pump arm ?

Speaking of CrossRam Intakes...
The Menance, if I may, I have an inquiry for Edelbrock...
Question:
Can the Edelbrock AMC CrossRam Intake Manifold be made
with a "Rear Central D/S Carb Bellcrank Relief Pocket"
to accommodate the Driver's Side Carb facing "backwards"
like on the SBC GM & Offenhauser CrossRam Manifolds
which may provide "more symmetrical mixture distribution"
and "compact" central location of Linkages & Fuel Lines ?
Was or is there a reason Edelbrock did not on the AMC CrossRam ?

It could have been made that way back in the day if that had been proven to be a better design or if that was what AMC or the race teams back then had asked for. One of the guy's who could probably answer that question retired from Edelbrock earlier this year, and the other person (Vic Edelbrock) passed away in 2017.
