Technical Intake manifold plates, ie like exhaust plates made for building headers that

That you could weld to?

I’ve seen several places selling exhaust pieces (don’t recall the proper name) but is the something similar for intakes?
Ya know, like the flanges-maybe?- that one would bolt to the exhaust of the head, then weld and build your headers to.
Thanks

 

Hell's Gate Hot Rods has them for some traditional engines. Bonus is that they are an Alliance member.

I bought a set of the intake/exhaust flanges for my straight 8 from them, and they are cut quite nicely, IMO.

 

Thank you!

 

There is a US company which makes both intake manifold and exhaust manifold flanges but unfortunately I can't remember their name. I have a set of intake flanges for a 401 Nailhead which were incorrectly ordered instead of the exhaust flanges. Quality and flange thickness was good but they just didn't suit my header project LOL
If I can find any details I'll get back to you.

 

Thanks to @Damon777 the penny has dropped and Hell's Gate was where mine came from.

 

Shoot, nothing for a SBC.

 

I made my own 50 years ago as a teen building the hemi for my Willys! Maybe one of the first tunnel rams ever? Designed it in physics cl***. Worked but not very practical. 20 years later I rebuilt the car (had been sitting torn down for 15 years. Lucky I didn't kill myself in first build. I rebuilt the manifold to a more conventional single plane style. Even had heat X-over! Never finished this, adapted a factory cast iron one for my Holley 3-bbl and been driving that ever since.

 

In reality its suppose to be used with their two piece intake manifold set ups. More of a oval track thing I do believe.

 

Try looking up intake manifold spacers for the small block, might make some of those work.

 

Seems most people make their own plates.
I had a guy, modify a small block Chrysler manifold to fit the Studebaker engine.

He made his own plates, because...no one else did. Made the plates, welded them in place, remachined the manifold after welding.
Some internal port filling (high dollar epoxy) was also required to make sure that the ports were smooth, and didn't have any odd turns or pockets in them.

If you look close (click on the picture), you can see the welds.

That's intended for use on a tall deck block with 18-degree heads.

Tough to get something like that to fit on a run of the mill SBC, especially since a standard head would be lacking the necessary bolts around the ports to secure the intake manifold.

 

Way WAY back there was the Crower U-Fab manifold kit and others like it. Good to know there are flanges available for some cars. But, with the sophisticated cutting equipment available today, chances are there is a shop in your town that can make anything you want. You could start by copying your old manifold or using manifold gaskets as a pattern.

 

For the hemi, you might try calling Hot Heads. I got an 8 deuce Crower U-Fab style from them about 15 plus years ago for 51 392.

 

So, I’m not out to build an intake.
This is more of an exercise to see “what if”.
See I received my Vizard book on porting and building an affordable flow bench.
I haven’t had much of a chance to read though the whole thing yet, but at work I got to thinking (always a bad thing) if intake “runners” were on the intake ports, it might be a more accurate representation of flow gains.
What got me on the idea is something I read in a HRM as a kid, and how header shape, size etc, changes exhaust flow.

Just something to satisfy my curiosity.

edit: came to me I have some parts left over from my -(forbidden subject)- days.
I don’t have a bandsaw to slice the intake mount portions off I can adapt to, so need to see what I can do getting creative with a jigsaw.

 

Here is how I did it for my 230cuin Chevy 6.

Mike VV,
Now that is some beautiful work,,,,,,very impressive !

Tommy

 

Thank you much Tommy.
It's been sitting a while, not complete. As of next week, the wiring will commence (headlights to taillight's). hopefully be done in a coupla days. Then I can move on to the exhaust, and get it finished, so I can drive the car.
It will be my daily driver when complete.

There are online services that will laser and plasma cut shapes out if you provide a CAD file.

Some of them will create the CAD file for you for a fee. If you already have intake manifold gaskets you can send them that as a sample pattern they can draw from.

Send Cut Send is the only one I've used personally and I have only used them for parts, not CAD services.
