Default Re: Rochester Dualjet Carb

Interestingly enough, a few late production 1969 GMC pickups with 305 V-6's were factory equipped with Rochester 2G's. However, a 2G and a Dual-Jet are 2 different carburetors. The Dual-Jet is basically the front half of a Quadra-Jet with no secondary's and came out in the 70's as an emissions-tuned carb. for Buick V-6's and other small GM V-8's. Some of the early ones actually bolt to a 4bbl. Quadra-Jet intake manifold. I wouldn't run one, I think you will have problems bolting it to the 305's intake manifold and it's likely calibrated way too lean for a 305 anyway. The WW is a great carburetor and is just the right size for a 305 as AZKen pointed out. The 351 and larger V-6's are a different story, they run very well with the 500 cfm Holley 2300.
