I have an Offenhauser 360 degree dual plane intake on my car and I've had a couple people at car shows tell me it's a rare intake worth quite a bit of money. I've never seen another one, but I'm not convinced it is actually rare. Anyone know? If it is rare, what's it worth? Thanks.
No, they are not rare. Offenhauser still makes them. You can order one from PAW for about $225. It is unique in design. I don't think any other intake manufacturers make a similar one. I had one on my 429 about ten years ago.
Offenhauser was big in the 70"s. However I don't think they are that rare, and or that high dollar. The Mustang I brought had one on it. But I'm not even thinking of useing it. I'm got a Cobra intake, that's going on the new motor.
My brother runs one on his '65 289 with C-4 auto. The car runs very well with plenty or torque and horsepower. As you may know the carbureator primaries and secondaries feed separately through a split port to each cylinder port. I think this helps keep the velocity up for the carbureator primaries when the secondaries open. My brother paid $50 for his which was cast in 1967 or 1968. I would use it in good health.
