    I have a 85 SS with a 400 small block with about 400 hp, I had a 750 holley hp on it but it seemed too much and didn't have a choke. I want one that will do good and start easily, my wife wants to drive it to and from work on some days.
    What are yall all using for carbs? Anything from around a 600 cfm to a 650 I think would do me good. Im not racing it just a good daily driver with some HP and Torque.

    My vote is for a quadrajet tuned specifically for your setup. Check out www.quadrajetpower.com. He's a small shop in the Texas hill country. He's a member on here. He can supply a core.

    I realize this might not be a good fit for you since you have a square bore intake. I agree 600-650 cfm should be the right size. Watch out though. If you go get a new 4160 Holley it will be jetted too lean for that 400 out of the box.

    There are formulas to determine proper cfm carb for your engine, A 750 will work but what you have is basically a race carb. What ever you put on I would suggest a electric choke w/ vac secondary's, set up for your engine.

    a 750 or 850 quadrajet only feeds the engine what the engine needs, for street driving you cannot beat a quadrajet

    I say put some split Dominators on it, might be a little much though.
