Carb for 340

A-Body

Thank you for the correction.....

"Simple Way"

In one of our {slightly modified} 340's, we are using a Carter AVS #4933S
{630 CFM} off the 1970 340 {Manual Transmission} Engine.
* Primary ......... 1 7/16"
* Secondary ..... 1 11/16"

Mounts perfectly on a square-flange Intake Manifold, on one our
street-use vehicle's > 1970 Duster 340 ~ 4-Speed, with 4.10 Gears.

The Carburetor came through with .101" Primary Jets and .095" Secondary Jets.

We changed the Primaries to .104" with a .070" x .042" Metering Rod.

The Secondaries, we changed the Jets to .098"

Runs great, and has a fantastic throttle response.

There was no need to spend $$$$ on a new fangled Carburetor.
