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?

Tell me about it! Does it really matter THAT much that you have to use only carb parts that came on a MoPar? Or not use them at all?!?! Holy Gez - Us!

1965 Chevrolet ~ 327/300 HP

AFB {3721S; Manual}
Rated @ 665 CFM's

Throttle Body Sizes ......... 1 9/16 " x 1 11/16"
Venturi Sizes .................. 1.250" x 1.562"
Primary Jets .................. .995"
Secondary Jets .............. .067"
Metering Rods ............... .063" x .069"

This AFB was regarded as one the best Carter Carburetor combinations
for the 327/300 HP Chevrolet engine.

Though rated at a tad lower in CFM's than the 1962 thru 1964 AFB {680 CFM}, this Carburetor was an excellent unit for the 327/300 HP Engine.

Performance Recommendations

To 'richen' this AFB by {12.3%}, {.071"} Secondary Jets were
recommended.

For better 'Cruising Power', a {.104"} Primary Jet and {.076"} Metering Rod
were recommended, which made the AFB {1.9%} Leaner.

For improved 'Power', a {.104"} Primary Jet and {.055"} Metering Rod
were recommended, which made the AFB {31.3%} Richer.

with a 1963 and earlier Hot Idle Compensator {#169-43S}

Also, with the Rochester Tri-Power Unit {767 CFM's}, this 389 Engine
combination put out an additional {+23 HP} to 348 Horsepower.

This Carter AFB on the A-Body 383/280 HP Engine was listed as a
'restricted' Carburetor at 525 CFM's, due to the smaller {1.313" Secondary Venturi}

Recommendations were to step up the Secondary Jets {one size} for
Street-use {#120-371 ~ .071"}.

And, to go up {two sizes} for Track-use {#120-175 ~ .073"}

------------------------------------------------------------------------------------

When using the AFB {#3447S} for a Single-Carburetor on the Small-Block Mopar.

1} Re-adjust the full-throttle arm, as it comes from the factory set at
15* before closing at W.O.T.

2} Change the Primary Jets to .089" {120-159}, as the Jets are too rich
for the Small Block.

3} Change the Secondary Jets to .095" {120-167}, as the Jets are too lean
for the Small Block.

4} Change the Metering Rods to 16-75 {.0635" x .053"}

5} Replace the Secondary Clusters with {58-151S} and {58-152S} from the
1963 {mid-Year} and 1964 ~ 426 Maximum Performance Engine AFB #3705S

Several NHRA Stock-Class Racers flow tested this AFB, and were able to
generate a {517 CFM} air-flow at W.O.T.
