Re: rochester 4jet

According to the two Rochester books I have, it's a model 4G, Rochester's first 4 bbl carb. Used from '52-'67. It's a square-bore design with dual side-hung floats. If you're looking for the best carb for off-road, you need to update to a Quadrajet, which is also known as model 4M. It is a spread-bore design with a single center-hung float. I'm running the Edelbrock Q-Jet #1904 on both my Jeeps with great results. The only thing better than a Q-Jet is fuel injection.
