I have a large ventura carb with very low miles. I just happened to get it buy a fluke. Usually when you order a rebuilt carb they for any six they give you the one for the 230/250 since those engines were the most common and those are the most common cores the rebuilders have. In my case I ordered a carb for a 250, and they gave me the larger 292 carb. However, I'm using a Holley/Weber, and plan to stick with it. Send me a pm is your interested.
Boo
PS
Please don't tell anyone I put a pinto carb on my chevy
