Really,

How about another Thread, on what Cylinder Heads should I use
on my stock 1970 318 2-Barrel.

Or better yet, what's the biggest Camshaft that I can put in my
1975 318 2-Barrel to help me go fast.

Stupid is as stupid does. You ever heard of parts swapping? What if you need a certain size metering rod or jet? Now you know what to look for in other makes that used Carter Carbs. Damn. Special Ed?

I admit......sometimes he's fulla hisself. But he posts a ton of info. Even the Quadrajet info is not useless here. Open your mind, Beavis. lol

1962 Chevrolet Corvette ~ 327/250 HP

WCFB {#3191S; Manual} or {#3120S; Automatic}
Rated @ 425 CFM's

Throttle Body Sizes ......... 1 7/16" x 1 7/16"
Venturi Sizes .................. 1.062" x 1.250"
Primary Jets ................... .086" {#120-163}
Secondary Jets ............... .070" {#120-222}
Metering Rod ................. #75-1586
Pump Jet ....................... .024" {#48-2885}
Low-Speed Jet ................ .028"

The 'First Year' 327 in the Corvette. Chevrolet goes with the 'basic' WCFB,
for the Base-Model 327.

The WCFB is a reliable Carburetor, and is again used for the '1963' 327/250 HP
{#3501S; Manual} and {#3505S; Automatic}, as well as the '1964' 327/250
HP Engine {#3697S; Manual} and {#3693S; Automatic}.

Though reliable, the WCFB is not regarded as a Performance Carb.

In 1965, Chevrolet switches over to a Rochester 4GC {486 CFM} for the base 325/250 HP Engine.

1966 > {#4199S; Manual} and {#4120S; Automatic}
1967 > {#4294S; Manual} and {#4295S; Automatic}

AFB
Rated @ 470 CFM's

Throttle Body Sizes ......... 1 7/16" x 1 9/16"
Venturi Sizes .................. 1.063" x 1.250"
Primary Jets ................... .089"
Secondary Jets ............... .073"

Though advertised as a 'special' 500 CFM AFB, it was basically a
good performing 4-Barrel for the small-cubed 273.

Several NHRA Stock-Class Racers flow tested this AFB, and were able to
generate a {517 CFM} air-flow at W.O.T.
 
1965 Plymouth/Dodge ~ 383/330 HP and 426/365 HP 'Street-Wedge

AFB {#3859S; Manual} and {#3860S; Automatic}
Rated @ 566 CFM's

Throttle Body Sizes ......... 1 7/16" x 1 9/16"
Venturi Sizes .................. 1.186" x 1.313"
Primary Jets ................... .089"
Secondary Jets ............... .0689"
Metering Rod .................. 16-127 {.0615 x .058" x .055"}

Again, the same combination as the 1964 Engines.

1963 Pontiac ~ 421/353 HP

AFB {#3547S; Manual} and {#3545S; Automatic}
Rated @ 625 CFM's

Throttle Body Sizes ........ 1 9/16" x 1 11/16"
Venturi Sizes ................. 1.186" x 1.563"
Primary Jets ................. .0935"
Secondary Jets ............. .071"
Step Up Rods ................ 16-126 {.0675" x .055"}

The 'First' year for the 421 with a single 4-Barrel and 10.75 Compression Ratio.

This same 421 with a 'Tri-Power' {939 CFM's} set-up comes in {+17 HP} with a
370 Horsepower rating.
-----------------------------------------------------------------------

1964 Pontiac ~ 421/320 HP

AFB {#3650S; Manual} and {#3651S; Automatic}
Rated @ 575 CFM's

Throttle-Body Sizes ....... 1 7/16" x 1 11/16"
Venturi Sizes ................ 1.186" x 1.563'

Pontiac steps down the 421 {-33 HP} down to 320 Horsepower, and
goes to a smaller Carter AFB, as well as lowering the Compression Ratio
to 10.5.
------------------------------------------------------------------------------

1965 Pontiac ~ 421/338 HP

AFB {#3895S; Manual} and {#3898S; Automatic}
Rated @ 575 CFM's

Throttle Body Sizes ......... 1 7/16" x 1 11/16"
Venturi Sizes .................. 1.186" x 1.563"

Pontiac again stays with the same Carter CFM rating combination for
the 'big-cubed' 421, but the Horsepower increases {+18 HP} to 338 Horsepower, as a 'bigger' Camshaft is now installed in the 421.
 
Carter Carburetors

1965 NHRA and AHRA Rules and Requirements

Both, the NHRA and AHRA 'approved' the Carter #3447S AFB {600 CFM} as a legal replacement Carburetor for the 273/235 HP Engines.

This lead to many of the {F/S and F/SA} Stock Class competitors to cry 'Foul', and to deem the 273/235 HP with the Carter #3447S AFB as an illegal combination.
