Is the carb bolt patern different on a 364 than the 322-264. I just got another 4 bbl carb off of ebay that is supposed to be off a 57. The bolt patern is different than the one from my carb off a 56 there both rochesters 4 jets. I was wondering if this is right ,or if I just bought a carb from a different vehicle. I dont have the 4bbl intake for the 364 to check it yet.
