    My setup is Rochesters on an Edelbrock intake.

    I know one thing for sure, you want to plug the vacuum ports on the end carbs. They'd only give you vacuum out the upper nipple when the carb is opened. And the lower port wont give you much at idle as the throttle blades should be totally closed. I've got the lower one on the throttle plate section hooked up to the PCV valve.

    That's my take for what it's worth. Like Viking and lt1s10 I agree about the power booster, trans and distributor.
