So I recently pick up a 76 Chevy K10. The truck is almost road ready. I don't know much about Carburetors. I know by looking at the VIN it's a 350 and its a VIN L indicating a 4 bbl carb. not sure by looking at it if it's 2, 4, quadrajet, or any other type. Pretty sure it's the stock 4 bbl but not sure if it was ever replaced with something else. Suggestions, info. Thanks
