Be cautious of what manifold you use on a 283-2 barrel engine.
It was pointed out to me that these have small ports so some manifolds aren't a good
match.

What you
Right, you can calculate for 100% VE and you probably won't get it, but if
you calculate for 75% VE you definitely won't get it. You probably wouldn't
even get the 75% you think you are trying to get because VE is influenced by
more than just the carburetor.
Again, the key is to *be realistic*
Without meaning to deflect the technical drift of this thread, I had a
thought:
Whatever happened to those old Carter (WCFB?) and Rochester (4CG?)
four-barrels that I remember coming with up-rated 283s? They flowed far
less than 600cfm -- nearer 400 or 450cfm, I think -- and seemed to do the
My experience has been that the older intakes are worth $$$ only to those who want or
need them for a specific reason; I had a '64 WCFB intake and a '66 4G intake for a
long time before finding people (both list members, incidentally) who were interested
in them. Same goes for 4G
Brad,
Makes sense to me, although I seem to recall hearing that these oldies were
getting expensive -- probably from someone who wanted to sell one to a
restorer. They can't be rare -- they made zillions of em. And just about
as many versions, each requiring a different rebuild kit! Were these
Unfortunately the 4Gs came with an attached aluminum tag that contained the pertinent
info, and the tags were prone to being damaged or disappearing. 8^( I keep my eyes
open at swap meets so maybe if I find one that still has its tag I'll take a flyer on
it. Of course, there's no guarantee
Sounds like Rochester should have taken a page from the mattress industry:
Do not remove this tag under penalty of law...!
I tried Googling Rochester 4CG + rebuild kit and got some useful-looking
sites. I didn't have much time to look around, but I did find that GM used
4CGs on big block
WOW!..thanks everyone for all the information!..I will let you all know how
it turns out...performance wise!..I really missed this list!!!
Thanks

, but to be realistic about what RPM you want to try to get 100%
VE at.

Hi Dale,
By now you probably saw my previous message, which also said that I agree
with you but in a different way (Even though I called you Brad. Sorry about
that.).
I think the main thing is to be realistic about what RPM you are trying to
achieve 100% VE at. Most street-only cars don't ever
Hi John,
I did the same thing on my '64. Used the Edelbrock 600 CFM 4 BBL. Does get the job done grin.

A 283-2 isn't going to take much fuel to get it running. Probably the
smallest 4-bbl from Edelbrock would be their 500cfm unit (#1404). Another
choice would be a Holley 390cfm (#0-8007) for a small engine

What you are supposed to do is *be realistic* about what max RPM you will be
running at, and find the CFM that will get you 100% VE at that RPM. Using
the formula to find a carb that will get you 75% VE at your max RPM kind of
defeats the purpose of using the formula if you ask me.
Now, it's true
