Thanks. I thought that setup was pretty slick back then. It was set up for a 250 shot.
But that pic is probably close to 20 years old.
That's a cast iron '65 intake.
I replaced it a long time ago with one of the limited first run 66 Aluminum Intakes that PY did.
You could just throw some plates under your carbs like OMT did if you needed & wanted a easier nitrous solution.
After I pulled that '65 Intake off I briefly considered putting it on another 455 & replacing the fogger nozzles with fuel injectors to do something different- but I had other project irons in the fire that took precedence.
It's now just a unique semi-exotic decorative piece sitting on a mock up engine with some 3D Printed carb bodies.
