Original 289 Trans Am Intake "Linkage?"

[TA Coupe]

I finally found a picture in my files of the heads that Randy is describing below since a lot of people don't believe they exist.

   Roy

    Doug Roy has cylinder heads that few know exist. They are indeed canted valve heads BUT they have 289 size ports and accept 289 / 302 intake manifolds. So Roy uses the 289 T/A intake on this "special" set of heads. To fill you in a bit , Ford want to do a "low cost" boss engine for '70 and built some prototype parts . I have the Engineering proposal paperwork . The program wasn't enough of a saving to warrant it . Some of the heads "escaped" and Roy had an engine built with them. They have conventional "style" Boss exhaust ports but are down sized a bit. Really cool and REALLY rare.
   "67,8,9" dual four manifolds all had the carbs facing forward. In the begining , the Ford linkage was used with BJ-BK carbs. Later the teams made their own versions which used "heim joints" ( or spherical rod ends) . Most used steel tubing for the "linking" between the rod ends. Mine was made by Shelby Racing Company and was one of the first to use aluminum hex stock. The next year (70) dual quads were illegal.

They look a bit like the C302 Motorsport aluminum heads although I think on those the top of the port is high and raised above stock location?

Also the location of the port is low like on the 2v Cleveland heads.

  These heads are another example of how LITTLE we know of what was made by Ford. The aluminum '73 wedge heads Roy had are another example and there were 2 bolt main aluminum blocks ( low performance) 302 blocks made and tested too. Stuff like this what I like to chase after and why I know it exists. The challenge is correctly identifying "why" it was made via Ford paper trails. Many like to elude to these parts as exotic or Holman Moody parts when reality is they were a design study for a particular or possible project. Not every experiment worked so many never saw the public eye.

I had a special intake casting that came out of Southern Cal. You must be in the epi-center of special castings.

The Dearborn, MI, vicinity is like a gold mine also.


What are the valve sizes in Roy's heads?

These are probably common compared to those canted valve Windsor Cleveland hybrid heads but a friend of mine has a set of 2 Barrel aluminum 351 Cleveland heads. XP part numbered if I remember correctly. He said they were saved from a dumpster. I was holding one of them in my hand.

  The number would have been XE as XP was used by the Automatic trans division. There is another great example , thank you! As I always say "EVERY" part was experimental at first. I have XE fan belts , thermostats , brackets , hoses, etc. that are very close to "production" parts on various engines.
