Olds Big Block 2x4 Intake

Bought this a few months ago for $3 as a joke and now it is time to turn it into weatherstrip kit for my 442.

It is an Offenhauser. Sounds German. Germans make the Sham Wow. All threads are perfect, no repairs, no cracks. It had been bead blasted and is ready to guzzle gas.

I am looking for $200 plus shipping. I accept Paypal, MC, Visa, and Amex. Fla residents add 6% sales tax.

My number is 561-951-4831.
Andy

Here it is on my 65 400.

I wonder what the MPG would be in my Vista with a 455.

I need to go sit in a corner and let my desires cool off.

Maybe I'll have a flash of sanity.

They are mostly for looks, but if you use 500 cfm carbs with progressive linkage they will work and I hafta admit they look cool. Have one with twin 600 cfm's sitting in my garage and have been tempted to install on my 48

I don't think that was the cause of his motor failure!!!! And with the right carbs it would work fine!!!

Maybe you should re-read those posts... Nobody ever said that the manifold contributed to the engine failure.

If a motor is running rich or lean it can cause catastrophic failure. Dont need to re-read anything. Common sense.

But the other guy on the other thread appears to have spun a bearing.
His mixture was uneven, but his combustion chambers and valves look fine.
His dual-quad setup wasn't to blame for his misfortune.

Over rich will not cause failure other than black soot and a poor running Rocket.

Over Lean is a completely different story! Engine failure in the form of melted components can and will happen.

This can occur with any carburetor. There is absolutely nothing wrong with a 2x4 setup properly set up as any carb or series of carbs should be.

Absolutely true...

BUT, depending on the components, the carbs may provide WAY more airflow than the engine could ever use, and (this is the "properly set up" part), may provide worse throttle response and fuel economy than a single carb, with no performance gains. Like everything else, it depends on the details and on the knowledge of the builder. Slapping a dual-quad setup on there ain't gonna help someone any more than swapping a four barrel for a two-barrel will, and might hurt performance, unless well thought-out.

Man, you guys really need to start your own thread. Read this, no hardcore Olds guy is complete without this near mint conversation piece collecting dust on his/her shelf/ I am NOT a hardcore Olds guy, I am a car guy with dare I publicly say two, yes two Big Block Chevelles, and two, again two Nig Block Monte Carlos, and a 90 454SS truck that will run circles around 99% of the cars here.

Who cares if it works, it is cool. Plus you can close your hood with this intake. It has all the factory bolt holes to add the needed stuff other earlier intakes dont. Again, it is made by the same people that brought us the Sham Wow. Now I am not saying that you need beat up a hooker * to be cool, but come on man, this intake is THE coolest thing you can have collectind dust on YOUR shelf. Or mock up an engine on the stand, set this thing on. You can be cool without ever bolting this thing down.




* to make sense of the hooker comment, realize the guy hocking the Sham Wow not only used Made in Germany to sell a shammy that didn't work, he was convicted of assaulting a hooker in Atalanta during a trade show in 2009.

Hmm, seems like a stick has just been poked in the hornets' nest!lol

Hood will close but you need a pretty low profile air cleaner going from the one on my 67.

Your thread was hijacked!

jimbo, you would think someone would fixate themselves on how I got it for $3, not even two months ago. Glad you asked.

A yahoo comes into my shop and says he has changed every gasket and seal on his wifes 95 Accord but it still leaks oil. He says he will give me the intake if I can fix it. I told him if it was more than a $100 repair I would take a pass. Turns out to be a $2.87 VTEC solenoid gasket. Got my intake. His driveway is now spared the indecency of Honda drippings all over it.

There, clear, concise, on topic.

And yet, that has nothing to do with how many carbs are on the motor...

A motor is a pump, just like an air compressor. The volume of air under normal operating conditions is limited bore, stroke, internal passage size, inlet and outlet size. It will only use the flow that meets those parameters. The fuel setting is based on jet size and basic carb setup.

The ratings on the carbs are based on bench flow tests at a specified vacuum level! A simple general rule of thumb is Cubic inches x2 = CFM requirement at wot. Since we don't run @ wot all the time, your figure will be then multiplied x .80 (or 80%).

So, a 455 x 2 = 910 cfm @ wot. Then for normal operating x .80 = 728. Most people run a 750 - 850 cfm carb on a 455.

Therefore 2ea 500 cfm carbs jetted and set properly would work on a 455. I've also run 2 ea 500 cfm on mild performance small blocks. Car manufacturers started putting multiple carbs on big and small blocks before alot of us were born with no inherent problems.
