    What are the cars to look out for for a 71-74 850' carb?

    What are the online names for Ken and Mark so I can get in contact with them?

    Can a 750 carb be "ranged" into 800cfm

    Got a chance at a 750cfm buick carb and don't know if I should wait or buy it. Mostly because I don't know the logic behind getting a 850 and also I don't know what cars I can find them in (is it going to be real hard to locate one)

    Update..Ended up with a 750cfm from 1967 off a riviera .
    Looks good and clean ..7041306..

    All I need now is the spread bore adapter I saw one from Edelbrock for like $48 and another one from Speedway Motors for 15 bucks..
    I think I'll just keep an eye out for the 800 and 850 CFM, meanwhile this 750 should work just to get her running and plus I got it for 65 bucks. Thanks for everyone's help

    Ronnie, I may have a spreadbore to squarebore adapter. Is that what you are looking for?
