Odd '163 intake

[firstgenaddict]

Give us a straight down shot directly over the carb mount surface looking into the plenum and an oblique view from one of the front corners would be great (I want to see the machining marks in the secondary openings).
I beleive that it is a standard 163 with the plenum opening for the carb modified.

I think you can see the step where the secondaries were machined in instead of cast in, in the top right picture.
I have had them like this in the past, where the intake was modified to work with Q-jets without using a spacer/adapter.

That's all the images I have of this intake.

Julian - You've seen '163 intakes with a spread-bore pattern
from the factory before? That doesn't make any sense. The
'163 intake was an SHP item and Rochesters were not. I
thought this was an oddity, now I'm even more confused.

Steve,
Sorry for the confusion.
I have had a few that were "modified" to be used with a Q-jet carb. They were not factory production intakes. One of them was done using hole saws to cut the larger openings, because the guy didn't have a boring head for his mill. You can imagine what it looked like.
Some people just won't run a Holley carb and have to have a Q-jet to be happy.
Again, sorry about the confusion.

some stock car classes required q jets some required iron manifolds.

Here's an original '163 intake. Guess someone could have
used a hole saw or similar to open up the intake in question
for a Rochester. Sure hope they didn't try to run that
setup against a set of oval port heads.

I've run rectangle to oval many times. As different as the ports are it will still run unbeleivably well. Oval to rectangle works real well.
