I have a 750 dual feed, vacuum secondary carb. I located a body from a 600 cfm carb. Can I swap just the body of the carb to make it a 600 cfm using the 750 base and bowls.
No, it wouldnt be a 600cfm more like a 670 and some work will need to be proformed to the main body Why do you not want to use the 750?
I am running the the 750 now. On paper it is suppose to be too large. I have to admit it is running good.
the vacuum secondary will cancel out the to bigness of the carb. the secondarys will only open how ever much is needed.
