What's a 4 barrel centre head?

 Well, as a guess, center, between the heads! Intake manifold I am sure he means.

I learned something new today. Centre head, steady bearing and bottom pan are all new to me. Ground grips was a common term here when I was a kid.

Center head is often the term used here on the East Coast for an intake manifold although I also heard that a few times in Ontario. In PEI a hangar bearing is called a "steady bearing" and an oil pan is called a "bottom pan". Snow tires are often referred as (by the old timers) "Ground Grips". Took me a while to learn some of these terms when I worked in service here. A hood is still called a "bonnet" here too. I've also seen "tires" spelled the English way "tyres".

 A steady bearing in my parts growing up was called a carrier bearing. When I first started in my field, I asked my GM parts guy for a carrier bearing and he didn't know what I was asking for. The intake was known as a "dome or battleship". I was in Brampton in '87 and went to get a dome gasket for my uncles G-van.. what's a dome gasket? Oil pan was a base pan.

As for the intake? I would say it would be an equibore, "squarebore" for '64?

Hi Phil, welcome from Halifax. DonSSDD is likely right the 4 BBL of choice by GM was a Rochester 4gc. In my mind, since your 283 came with a 2BBL which they all did from 62 onward, you need to Google the casting number from the intake to find out what carb it was designed to accommodate. As a Cape Bretoner, we use to refer to the intake as 'dome' so I get the centre head name but have never heard of it Interesting how we all have different names for the same parts. Please don't let that deter you from posting!

I have a couple of factory rochester 4GC carburetors for a factory square bore manifold,  if one is of any interest to you.  will need rebuild.  if you are wanting a stock factory look that is.
