I have no idea what carburetor is on my 57 292, I have a feeling it was frankensteined.  Runs OK but auto choke is bad, and sometimes engine dies when I stop.  Will a Holley 7448 (http://www.ebay.com/itm/Holley-Carburetor-350-CFM-Maunal-Choke-7448-C-Factory-Remanufactured-/231383483318) work without modification, except of course I will need to go to manual choke?  If you have a better place to buy a carb for my Ranchero please post.

Thank you
