I would like to run some old Rochester 2 bbl carbs on a 3 x 2 set-up for a small block chevy. I have no clue what type of two barrel carbs I should be looking for. What years of vehicles were they on and so forth. If anyone is familiar with these carbs, maybe they could post a pic and give me some guidance on what I should be looking for at the salvage yard. Your comments and guidance will be appreciated. Thanks.
