Check Jon's website (Thecarburetorshop.com) I think that's right, anyway. He has a list of correct Carter carb numbers for various Chevy sixes, all the way up to the 194-292 engines from the 70's and 80's. There's quite a history of the Rochester/Carter dispute, dating back to at least the late 1940's when GM quit buying Carter carbs to run on Chevrolets and started manufacturing their own. The CEO of Carter vowed to sell a million replacement carbs for Chevy engines. After a few years, when the millionth Carter OEM replacement Chevy carb came off the assembly line, Carter had it gold plated and presented it to the CEO of General Motors. Rochester carbs were built to last through the warranty period for Chevy products, with little or no concern for longevity. Carter carbs were designed and built to be repaired, numerous times if necessary, and they last much longer without the rebuilding difficulties usually encountered by Rochesters.
