    Ok here it is,I have a 48 stylemaster 3 spd with a 235(1953 block),848 head(56-62).You guys have been great sorting that out for me.I pulled the carb its a rochester single barrel,none of the serial numbers match on it.I want to replace it.I need to know what model I need,part number ect.Seems like who`m ever had the car before me,had a lot of parts from differant years and made them work,wich has left me hunting for info,not being able to match casting numbers ect.I want to be able to go to auto zone and tell them exactly what I need(I dont trust there knowledge in getting the correct carb)Thanx for your time

    Some (not all) of the Rochester B carbs have a four digit number stamped on the gasket surface of the base plate, like "9522". It's the last four digits of the carb's original tag number.....you know, the I.D. tag that got thrown away the first time someone had the top off of the carb. Clean the bottom of the base off and if there's a number there, we can figure out an exact application.

    Inside the carb is the number 7004510(near the float) on the outside 7003536-c-33 RP. Also the number 4519 near where the air cleaner would attatch

    What do you suggest as a "real parts house".There are speed shops in the area,but they wont know any more than I do at this point.They all mess with newer cars and they do charge more for parts.I just want the info so I can just go where ever and purchase the carberetor and not depend on a counter person to help me figure this out.

    Great! Thanks so much!
     
  12. BC stands for Bull Crap, I think. If you can find a Carter YF for a Chevy six you'll be much happier. More horsepower, better economy, and less likely to leak. Some info on what numbers to look for over on Chevytalk.org -

    why do you want to replace it? Because it needs rebuilding? If that is it, then what you need is a carb rebuild kit. If you dont know how to install one, people here will be more than happy to help im sure.

    If your carb is actually junk (not enough info, but if its cracked or rusted tight) then you can find a used one easily and rebuild it cheaply. I dont know this for sure, but from what I have reasoned out from this post, it seems that you are intimidated of rebuilding what you have. Dont be. These things are simple. If you had the mechanical inclination to remove this carb from the manifold yourself, then with some patience you can rebuild it on your own too.

    Just buying a new carb because your existing carb needs to be rebuilt wont grab you much respect around here. Plus its a waste of money.

    As far as autozone, I had no idea you could get a reman 50's 6 cyl carb over the counter at these new chains.

    I agree. It aint that tough. Snow up to our elbows so you arent driving anywhere this afternoon.

    Its only a potbelly Rochester. Either rebuild it or throw it in the trash and get another. Nothing wrong with learning something new

    Keep in mind that there are two different size bolt patterns used on these over the years. Make sure you get the right one. carbs intended for the 216 were about 2 11/16" between the studs and the 235 is about 2 15/16" between.
