SOLD - I have a used Offenhauser 5486 intake manifold for a small block Ford V8 (260, 289, or 302). It’s a single plane manifold designed for two four barrel carbs (Carter AFB or Edelbrock Performer series carbs are recommended). Here are some more detailed specs from Summit Racing: https://www.summitracing.com/parts/ofy-5486/
$125 OBO - There are not a ton of these out there to get comps on, so if I'm out to lunch on my pricing, let me know. I'm selling it for my cousin.
