Re: Offenhauser dual port intake
I haven’t been able to post pics yet.
The outlet ports are split top to bottom. It’s a 4 hole split plenum and the primaries have a separate path to the outlet than the secondaries.
I have heard they were made during the gas crunch.

After some research it turns out that offy made these for mopars amc ford and others. Even some for inline 6’s
Any experiences others have had, I would like to hear about.
If they made that many,I’m sure someone here has had one.

Re: Offenhauser dual port intake
yeah thats the one i had on my 69 amx 390
seamed to work ok had good low end power
think it would work best with a square bore carb ....been a long time but think i was running a carter
i could see it lacking in top end ,so would want to run a mild cam
and i think if you stay out of the 4bbl it would improve intake swirl and improve fuel economy (it was on the car when i bought it so can't say it was better
