Thinking about updating the old Rochester and wondered if anyone has this carb? I have a failry stock 235 in the 59. Now I know a modern carb will be newer and I would hope an improvement but just wondered what others thought of this setup before I run out and buy it as it isnt cheap. Does it offer power or fuel gain or just be a less leaky hopefully issue free set up? I drive in town and freeway often if that helps.
