There is a Carter YF designed for a Ford inline six, 240 or 300 cubic inch, and yes, it will run VERY rich on a stovebolt Chevy. Don't try to rejet it- - - -get the proper Carter carb for your application. There are a lot of other internal differences besides just the jet size. RUN!- - - - -do not walk away from anything that says "Rochester" om it!
