An Intake Jay didn't test

[thatdarncat]

I spotted this at the MSRA Back to the 50's swap meet today. One I haven't seen before. I didn't ask details, anyone know the story? I'm guessing homemade from an Edelbrock Cross Ram? I posted it here in the classifieds just because it was for sale.

That looks like it would flow horrible.

Kinda looks like an attempt at an old nascar type manifold back in the day..

Definitely looks to be homemade, even the top. And I'd agree that it looks to be based off of a crossram. AND I would agree that it probably flows TERRIBLE. The intake ports are located clear to the outside. The air/fuel would have to make one 90* bend and then a 180* bend (!!) just to enter the port   That is unless the entire area in the plenum is cut open, exposing the tops of the ports.

It would be interesting to see how the area under the carb is modified.

Maybe they  were going for something like this. LoL.  Looks more like a $1500 conversation piece to me.

Thats what I was wondering. If he had milled the tops off the plenums, it would probably work pretty good.

Yes, an attempt to mimic a NASCAR intake, of sorts. Heck, even if the port flows were good and even across all eight, it would make a lousy intake for most engines. MustangTek has a few other real NASCAR manifold listed and depicted here: http://www.mustangtek.com/FordIntake.html

Take a look at the very bottom for SK-18454. Another box-type intake but with a much lower profile and likely tons less plenum area.  The lidded SBF Cross-Boss (for a Boss 302) and the Shelby-type box intake were used in the old Trans-Am series to some extent yet for tight cornered tracks they came up short due to the need to reduce rpms and then quickly hit the go pedal. Those big plenums weren't kind at lower rpms. Interesting too is that most FE powered resto NASCAR race cars only use the more conventional intakes and not the box-top style.  Most resto cars, in single 4-barrel form, show up with C6AZ-9424-M, better known as the Sidewinder intake IIRC.

Maybe it has strategically placed pop cycle sticks in it to enhance (direct) flow.Early Mopar Pro/Stock R&D manifolds were full of wood.

Funny you should mention that, many years ago I rebuilt a pair of Mopar race hemi Holley carbs for a local collector. To get a little background on them since info was scarce ( long before the internet ) and confirm the staggered jetting I talked to a long time Minnesota super stock racer with a '68 Hemi Barracuda. He told me the exact same thing, that back in the day they would epoxy popsicle sticks inside the intake manifolds and that every time they tried a new cam it could mean a redo of all their work.

I don't mean to hijack anything here, but here's another intake. Jay, I did not see this one in your book, I don't know if you have ever come across one or not. Maybe you have run one of these at some point. Anyone know how well this one works. Maybe Joe could chime in too.

That one is the 2X4 version of the single 4 Weiand intake that I tested.  It is similar situation to the Offy 360 vs the Offy 2X4.  The single 4 Offy 360 and the 2X4 Offy worked about the same, so I would expect the 2X4 Weiand to work about the same as the single 4 Weiand.  Which is to say, it would be horrible intake

Wonder how. The Parker racing 4v Cleveland funnel web would do ? I have one and had it on the PSE base but never ran it down the track. I have heard there excellent manifolds though. . It will def get mounted to my new adapter for a spell..   

[jayb]

I'll bet the funnel web would really work well...
