Technical offenhauser dual q jet 4 barrel intake anybody seen one before

I think that one falls into the hen’s teeth category, it’s for the 348 W-motor.

 

yes quadrajet sound is awesome..my friend called them quadrabogs...guilty of the air cleaner flip here also....

 

Hey Folks
I am installing a dual hi-rise setup and came across this discussion about Offy on the Hamb.
I have an Offenhauser Square bore dual hi-rise intake in near-mint condition and I have 2 Edelbrock AVS 650 carbs and was searching if the carbs would be too big on a mild 327.
Back to the intake.
I picked the intake up on the internet it is a dual carb square bore hi-rise, not the low rise which is part#5253 from 1965 I have never seen a dual hi-rise square bore and that's why I bought this, being a square bore each equal size hole in the intake feeds each runner I thought that would work well, I could not find any information on the intake. The part number on the underside had been milled off kinda strange well 2 weeks later I still have no information on this intake so I called Offenhauser and spoke to a fellow named Vince and when I mentioned this intake, he knew everything about it. Back in the day when the Offy low-rise was produced people installed a 2'' spacer for more performance and that's when Offy sent the 5253 intakes along with a 2'' spacer and cast the new square bore hi-rise which created a small problem you couldn't have a low-rise and a hi-rise intake with the same part #5253 so on the new hi-rise the part# was machined off. Today that hi-rise is now a dual plane, not a square bore, and is good for top-end but not low-end.
Now, would this be a rare intake?
I removed my 3x2 setup and will run the dual setup this summer for a change.

 

Let's see a photo of it and as far as the carbs go you'll be fine, the carbs don't work like a Holley and that's what confuses a lot of people, they draw on a signal almost like a variable cfm carb.
I've used two 600's on the short offy intake on a very mild 350, one to one linkage and absolutely zero issues, plus averaged 15.3 mpg with 4.11 gears.

 

Not a q-jet intake for the spread bore.

 

What an infamous end !

 

Do you still have the dual quad Qjet Offy intake, and do you want to sell? New here, and have no idea how else to contact you. =)
