Jay, is there an advantage to using a round throttle blade versus a oval/rectangular throttle blade like this?

Jay for the distributor, I've got at least 10 Mallory "old" ones you could butcher  a few for trial runs. Or a bunch of Ford Dizzy's.
If you'd be interested.

I dont suppose ya gonna make a set of those that stand straight up   

Always wanted a set stickin out of my hood

...

It's all about cross-sectional flow area for a given package size.  Even at 1,000 HP, a row of round pipes that size isn't going to be restrictive.  When you start making enough power to break dynos, you need to look at a  more rectangular runner shape to get more area into that same space.

Ford actually built a square piston (radiused corners) V8 engine prototype in the late fifties.  It was a design study to get the maximum cubic inches in a given block size.  The engine ran on a dyno (for awhile before the rings seized!)  I didn't believe the stories until I saw one of the actual piston / rod assemblies on an old-timer's desk.

That is an excellent suggestion, I had not previously considered that approach.  But I can see a few problems.  First is availability of the throttle butterflies themselves.  It would be very difficult and time consuming for me to machine those myself, but I can buy normal round throttle butterflies from Hilborn or Kinsler, which saves me that trouble.  Next, basically the same issue with the ram tubes; those are available in multiple sizes round, but any custom size like the ones shown in your link would be a do it yourself kind of thing, and I don't know how I could get that done.  Same thing again with a K&N style air cleaner for each runner.  Then finally, one of the design parameters for this setup is that it has to fit under the flat hood of a Mustang or Fairlane/Torino, and while I really like the idea that the interference between tubes could be reduced with this approach, I think it would make the whole setup taller, and I am right at the limit with the existing design for hood clearance.

So its probably a no-go, but thanks for the suggestion, the idea definitely opens up some new possibilities...

Thanks Richard, I will keep that in mind.

Sorry Ricky, not planning on that.  But you never know...

[Joe-JDC]

Have you tried to turn one upside down?  It would stick up quite easily if it fits.  LOL  Joe-JDC

"Then finally, one of the design parameters for this setup is that it has to fit under the flat hood of a Mustang or Fairlane/Torino,..."

It doesn't look to me like that rear throttle rod stand would clear the firewall of a Mustang. Have you verified its fit?
Not trying to be the negative putz here, but that is a LOT of aluminum. That has to be approaching 40+ lbs as a complete unit. I suppose not an issue if it's use is street oriented.

In the meantime I've been trying to get the 4V intake manifold casting ready to go.  Today, after some accelerated work at the foundry and the heat treat plant, I got the first two castings:

Why did you have the 4V intake cast in 2 sections? Or was it cut in half to check the casting?

[C6AE]

Beautiful raw castings, the casting simulation software is impressive. The information and explanation on sprues, cups and riser sizes duly noted... How fortunate to have an FE friend in the educational system specialized in sand casting process. Thank you Jay for documenting and sharing this process. Many thousands of dollars worth of education here. Excellent!

(My own experience with casting has been all about reading, studying, then trial and error. Mostly error, with cold shuts and stress and shrinkage from cooling being huge problems. But the successes are worth it)

Doug, as is the setup, including the throttle linkage, does fit in the engine compartment of my 68 Mustang, at least based on my measurements.  The export brace would have to go, though.  The other issue that just dawned on me recently was how to hook up a throttle cable.  I may have to reverse the operation, so that when the bellcranks go forward, the throttles open.  Then I could just loop a cable around from the front.  There's not really any room to attach one from the rear.

The intake is cast in two pieces because I want it to be easily disassembled for porting purposes.

[cjshaker]

A bellcrank would work on the back, but would be more involved in producing than your idea.

And I figured there was a reason for 2 castings on the intake...and that's a good one..lol

[JERICOGTX]

Got a chance to see the new cast intake in person yesterday. jay has it machined, and ready for the show. Very nice piece. FE guys should be grinning ear to ear, with this new stuff coming out. Should make a EASY 900hp bracket motor with this stuff. Could only dream of new Mopar stuff to come out like this.

Here are some pictures of the 4V intake that Jeff is talking about.  Also in the first picture you can see the 3D print of the cylinder head, with the revised, factory-style exhaust ports:
