"1975 Plyouth Duster" Model

[QUOTE='64 Cuda]I have an old book on Holley carbs, printed in 1980. It says "...there actually was a Model 3160 and it was a three-barrel carburetor. It was introduced for use on the large displacement engines of the Sixties, and listed under part number R-3196-1AAS. Rear barrel measured 1-3/4 x 3-5/8 inches and airflow was 950 CFM." That and a picture was all I saw about it in the book. It looks like it had a really large vacuum diaphragm for the secondaries.

Man, 950 cfm! That sucker was big! I think they had a 3150 model too. Does anyone know if the 3150 was mechanical secondary?
