Mike,
I have seen lots of intakes similar to the one you show. I like to think Ford was just having fun with the Chevy boys. There was at least one version that does have an "8" character. In fact 1967-1971 the are several versions of this base casting with different lettering in different places. The intake is very different than the 1966 and early 1967 design. The first design was a conventional two plane 2-4V. This design makes the system sort of a cross between a dual plane and single plane pseudo individual runner system at wide open throttle. Legend of the day in 1967 was that the Group II engines Shelby's car had put out between 440 hp and 460 hp from a relatively low rpm mild mannered state of development. This year I ended up with the a set of cylinder heads and the induction system that was claimed to have come from the Shelby/Titus Group II championship car at the end of the 1967 season that the Ford engineering number was hand applied and not cast in. It also carries a serial number as do the matched C6FE cylinder heads. By 1967 the parts on race cars were no longer just like those that were was sold retail to the general public. Check out the end of the 1967 season full mechanical 2-4V 600 cfm carburetors. The versions sold to the public came with two small (360 cfm ??) vacuum secondary carburetors. You can't see them in this image but the throttle shafts are Holley customs riding in bronze bushings. I am told that these carburetors were developed in 1967 for 427 cid powered GT40s by a long time GT40 expert. Except for missing a piece of rubber hose and three hose clamps this set up it supposed to be just like it was removed (the plastic wire tie is mine to hold the throttle link up and protect it.) at the end of the 1967 season. The man had the entire engine originally but sold the four bolt main C6FE short block to somebody to use in a race car decades ago.

Hand stamped engineering number.

Serial number stamped on both sides of the intake.
If it just wasn't so expensive to do, it would be neat to build up an engine and do some dynometer runs comparing the various Shelby 289 cid Ford induction systems they used or sold on a single engine package; 1-4V dual plane Holley (street and race), 1-4V ram box Holley, 2-4V ram box Holley, 2-4V Carter (street and race), 2-4V Holley (street), 2-4V Holley (Group II race), 4-2V 48 IDM1 Webers, 4-2V 48 IDA/IDA-1 Webers "parallel" design, and 4-2V 48 IDA/IDA-1 Webers "opposed"design.
