This is great research!  Some good links from 1109RWHP, Thank You! Good photos of the Dominators too.
I don't think anyone can question  the existence of the Dominators in the still photos that have been posted by Jon. I personally don't even doubt the fact that Mr. Kaplan may have tried running a drag race designed tunnel ram. Not being disrespectful in any way,  his engine building skills have never been the pinnacle of his racing legacy. Apparently it wasn't the "cat's meow" , especially as klvn8r stated "Kaplan barely even remembered the tunnel ram". It seems it would have been a high point in his recollection if it had worked out.

Either way, as Mike343sharpstick has pointed out, that hood bulge is huge and wide. I think its likely there were many different intake/carb combinations tried under that hood, including the crossram. Ken's manifold appears to definitely be another obscure piece of AMC history, but I'm not convinced we can be certain that "it is a true T/A piece" as Ken stated. At least with what has been presented. The following photo  shows a manifold which appears to be like Ken's used in a  Pro Stock. This certainly doesn't rule out it being used previously in a Javelin, but it might help answer why it had been modified so extensively.    (sorry, unable to credit its source)

My hope was to clarify that these parts did indeed exist, were actually raced
Ken, I wish you well in that quest, I'm sure something will come of your display, and of course here on this forum, the "Best" source of accurate period correct information!
Do you have any casting numbers or stamps left on the intake? The small photo I posted doesn't show much, but it looks to be pretty heavily modified. Back in the day(and even some now) alot of engine builders would have to cut the intake to head surface back and use plates to get a better transition from the intake runner to heavily modified heads. This was especially common with the Pro Stocks with their welded heads to achieve the port sizes they needed.
    I believe the later Wally Booth Pro Stock engines used an intake of this nature.  Do you have any history on your particular intake? It looks like it could be one of the Booth variety. Those runners look like they have been shortened (correct me if I'm seeing wrong) but are still awfully long for road race responsiveness.
I should have some photos in my collection of the Booth engines, I'll try to post them.

In regards to AMC intakes at the 2012 MCACN show, Jon Mello posted:

"Terrific! Would you please post some pics of the manifold and carbs in this thread when the show is over?"

Several of us have interest in the Javelins and hope we can see some photos. I received one photo from a friend in attendance,as follows

I recognize the crossram on the right, but maybe Klvn8r or Crazyamc can confirm what is shown on the left.

I will be assisting one of the second gen. on Saturday. I hope to be able to get around and say hello to the gang.
I understand that  Carmel's Tuesday Concours will have a contingent of HTA's drive over from the track. Should be worth the effort to see!

Welcome to the forum, Trans man.
   The computer I'm at right now has a very poor screen, but i believe those are Motor Wheel Spyders in  the photo. There is a Trans-am wheel topic here:
Check out post #46.

Its a sad tale about Dale Phelon. 
The auction house seemed to be very apprehensive about releasing any information about the car before the bidding began.
Maybe we will eventually see the car in the west coast group.....
How about it Robert? It would be nice to rekindle an old friendship with that car!

Great history on George Bolthoff.  Good reading and period photos.
Thanks Jon and Robert Barg!

That's some good "hands on" information Pigpen. Thank you.  The oiling issues will probably haunt AMC forever. That is a excellent suggestion about the Traco Lifter Retainer controlling the oil splash. As you are aware the Traco AMC intake has provisions for the stock rear PCV valve. The factory design is notorious for sucking oil up the PCV if a valley pan type gasket is not used. I don't use the pan type intake gaskets, and have never had an issue with oil being sucked into the PCV. I believe, as you have stated the Traco Lifter Retainer keeps the oil splash down and away from the intake. Just another example of the engineering that Traco is so famous for.

   It looks like there is also a photo of a "young" fellow doing some valve spring work here: under Reply#8. 
Very interesting info on the four bolt block, small journal/ large journal choices.  During that time frame, Traco apparently was "cutting edge" when it came to reciprocating weight. The stronger and  lighter weight Carillos must have made quite a difference in engine longevity.
   In the above article from Swede70, the AMC story from Jean Calvin, on page 171.  There is a photo of the valley of the AMC block. I see it has been modified for the single oil feed line that feeds additional oil to the gallery above the #4 main. I have also seen a Traco modified block that had four additional lines feeding that same gallery above each of the mains. As you know, the mains in the AMC's are fed after the lifters and cam bearings. These modifications generally help insure oil getting to the mains. Did Traco start off with the single line and ended up finding the need to use all four, or did you find the single line was sufficient?  I machined an oil log manifold in the valley for one of my AMC wet sump engines that feed the mains priority style and restrict oil to the lifters and top end.  I have had an engine failure with the single feed line in the past, but not 100% sure I can blame it on the oil feeds.
     As a side note, I also see in that same photo what appears to be the 1/4" studs in the valley to hold the special Traco AMC lifter retainer plate!

Thanks Mike for sharing all your research. This Flicker link looks like it will keep me busy for hours! The photos are spectacular!

    I'm not familiar with any of those eastern tracks, but you sure gave a good visual for me! I feel my stomach turning with that wall coming up!

I have some more engine questions for you.
    In recent years, it has become common practice for engine builders to use a smaller rod journal size when available.The smaller journal reduces bearing speed, cuts some frictional loss and brings up the horsepower some.  The Chevy 302 started life in 1967 with a small journal rod size of 2.000". In 1968 all small block production went to the large journal design of 2.100" including the 302.  The large journal blocks also incorporated the four bolt mains which were not available in previous small blocks.
    Did Traco choose to use the 4bolt/ large journal blocks over the small journal variety? I wonder if any power differences were observed on the dyno or track between the two. I suppose they had the option of using the 4bolt/large journal blocks and turning down the large journal crank throws to the small journal size.
    In general, were you in search of these types of smaller horsepower gains?
Thanks again for your contributions,

     Thanks so much. Those long hours must have been tough for sure.  The travelling really takes its toll also.  I would suspect your children learned to appreciate you even more when you came home.  As far as that big blur, that's probably a blessing too.  We have a knack to forget life's unpleasant experiences.....  It's nice to hear you are enjoying the "good time memories". We are too!
      You have a Great Father's Day, and a special Father's Day greeting to your Dad!

Pigpen,  I don't want you to think you are forgotten!   
Do you recall Traco using any of the Crane ported heads talked about here:  I would think they may have been worth a try on the Dyno if nothing else, considering their pricing, and availability.
