    i have a 85 blazer w/ a 350 and i put a edelbrock 650cfm carb on it and am having trouble with vacuum i believe.


    Whats the basic vacuum setup (i cant find it in the manual) does the vacuum off the carb go to the distributor or?


    Thanks!

    I think the big hose in front goes to pcv valve. the little left nipple goes to your vac advance. the others could just be pluged up.
    I think this is how it goes I just did mine but i don't have my truck here right now otherwise I would go check it.

    It hooks up to the driver side of the carb
