Do we Need another choice in Intakes for the 472/500

Are you talking about doing a manifold or a head ?

A head would be a waste of time a manifold might be something you can actually do and in the case of a dp manifold the only way to get to areas that cannot be gotten to.

you will need to continually force the slurry thru the head to remove material and keep it moving and it will take alot of material.

Ive seen the extrudehone process first hand and they use alot of the stuff to do a manifold.

You will not be able to get enough continual volume thru a plastic tube and auger to do the job.

You would need something designed to pump an abrasive material (concrete,gunite,jacking mud)

If you have seen what happens to the equiptment used for pumping concrete ,the pipes elbows and unions wear fairly quickly and the aluminum components wear even quicker and have to be made from something light so they can be moved around by hand.

all that said if someone wanted to rent a small pump and mix up enough material along with making a fixture to bolt a manifold to the pump and figure out how to con a couple friend to shovel the stuff back into the pump.....more power to them im sure it would do something.
 
no shovel required.
all you have to do is put the manifold on top of the hopper that feeds the pump.
Let the concrete fall into the hopper.
 
Might be able to do that depending on line pressure

might be a real mess too
 
easy as 1-2-3.
Pressure has nothing to do with it.
Bolt the manifold down to the hopper.
 
Hey guys this thread is on intakes, If you want to talk about extrude honing how about starting a new thread.

But for what it's worth you are wasting your time even thinking your going to come up with a cheap way to do it at home.

It's not going to happen, There is more to it than you think. It's much cheaper to just have it done.

Judging by the magazine articles I read on extrude honing, it doesn't seem to do all that much to a stock intake, or stock exhaust manifolds. but maybe it depends on which engine brand/manifold design.(?)
 
The ability to do anything to a stock intake or exhaust manifold is the difference to some in winning or losing.

What it can do to the edelbrock or similar manifold that cannot be ported in certain areas is what it is.

Expensive,I think so and the process has not gotten any less expensive over the years but it is what it is

Been busy but someday I'll get to finish it.

That's what I'm talking about.

:cursing: :banghead: NOW< my question is "JUST HOW HARD WOULD IT BE FOR EDELBROCK TO DO THE SAME DAM THING RIGHT ON THEIR ASSEMBLY LINE?!!!!!" :censored:

Been there. Edelbrock has been contacted a number of times about an RPM style caddy intake. I agree with JW, in that it's never going to happen.

One thing I can't stand is when people ask if a part works or not or ask if they should buy something and others chime in that they bought it too but haven't installed it yet. Thanks for nothing! At the risk of wasting your time with a little theorizing, why wouldn't a cross ram made of tapered tubing work with say, a pair of 500 AFBs or Holleys? Chrysler put them on engines from under 300 cid to 426 cid. Someone here also posted a link to a Mopar intake which was a box between the heads with intake passages inside. The plenum was the area above the passages. They crisscrossed like when you put your fingers together. This might be good for a Cad as the inlet isn't pointed upward anyway, right? Building a taper into the passages would be easy; every passage would have exactly the same volume and distance to the inlet.
 
I can't help wondering if in the near future it will be possible to make a composite intake using 3-D printing technology.
That would allow economical small scale production of a number of intake designs would it not?
 
Plain and simple crossrams do not work very well using a carb.

Those long runners have to carry fuel and air and dont make power very well compared to other designed intakes of the era.

Everyone (the big three) and id bet even AMC probably fooled with a crossram or rat roaster kinda thing.

That said,making one out of straight walled tubing or doing an aluminum one would really be a waste of time unless you were just after the look and at that point i say go for it.

What would work is an IFB intake

You would have to have a cad file of a complete intake manifold to do this and 3-d printing is not yet inexpensive and afik there are a limited number of machines capable of making something as large as a manifold.

I have seen holley and edelbrock manifolds made using SLI as well as a reproduction of a oldsmobile manifold that was being duplicated in aluminum from iron as well as a new canted valve chevy head and I understand there are materials that can be used to test the design but not to make a product for fulltime use and i may be wrong,however as limited as the number of manifolds would be they would not be cheap either way
 
On the subject of dyi intakes, I may have mentioned the car here before, but;

I have seen an all 'glass '55 Olds covert. The guy spent years building the car. Runs 9 flat or so, Real Olds engine, batten heads, methanol, etc.

He has made a number of intakes over the decades from fiberglass.

I've seen some demos somewhere where they have a computer/ printer plastic infection feed that can make some pretty complex parts. As it gets perfected and fine tuned I'm sure what it can do will increase and what it will cost decrease, just like computers. Who could afford or even get the type machines we have today vs just 7-8 yrs ago, and for about 1/5th the money.

Will try to find the article I saw and post link.
