After searching for an old Offenhauser #5489 intake manifold for quite a while I was able to get one through toomanmikes help here on FABO.
After sending it home I first thought I should glass bead it. However it tends to loosen it's luster.
But my oldest son Kevin had an idea on this. I took threw the intake in my Durango to a guy in the next town and left it there. Water polishing! Yeah right, water polishing!
Today he called me to say it was ready for pickup. I drove there and didn't know what to expect. After 40 years in this hobby I've seen alot but what the heck. Kevin knows me.
Opening the front door and there it was! Must be some other guys intake but no, it was mine! It was absolutely stunning!

What's your opinion?

Now I start to build that special 273 hp engine produced in the summer of 65 only!

Looks good and will preform the same. I had one of those on a 273 commando and it was awesome.

Ulf, I worked for McDonnell Douglas/Boeing for 33 years as a Materials and Process Engineer. We had various media blast cabinets in our lab. One of them was called Hydra-Hone. It used water as the carrying medium for any type of abrasive media that we chose to use. Many times I would use just the water on our aluminum parts and they turned out just like your intake. Excellent results.
 
That looks badass. That intake is an anomaly among intakes sorta like the Holley Street Dominator. It's got a dual plane plenum but the body is a single plane. That's why they called a 360, because it has the best of both worlds so to speak. It's a nice piece.
 
That appears to be aluminum vapor blasting/honing. Process has be around for a while and seems to be the way to go on non-ferrous metal. Gets it clean but doesn't alter the base material.
 
Job well done in my book, but it's a small book :lol:
