383 w 6 pack set up opinions?

A six pack is not really hard to tune at all. Use the KISS method to begin with. Start with the center primary carb. Once you have that center carb dialed in, you'll realize that it is 90% of the ball game.

When it comes to the secondary side, I suggest a 02 meter to let you know how lean or rich you are. What ever plate you change on one, you change on the other.

While a well tuned 6pack is a hell of a runner, the expense of getting one is huge by compare to a 4bbl set up that will probably do jus fine a lot quicker and easier.
With that said, I'm currently saving up for my carbs and linkages now for my S/B 6 pack.

They are very flexable and will perform just super in the listed RPM range you read about. Truth be known, it'll also make a stretch for a few hundred RPM in each direction of the RPM scale. If you have Hughes engines port the intake, you can really help the intakes flow.

IMO, it is a great induction system. It is hard to get a single 4bbl to cover all the bases of street, street strip in one size. The 6 pack does this. The total CFM of the set up is rated as a 2bbl which is different than a 4bbl. In 4bbl speak, it's 780 CFM. The difference is a 750 carb has primaries of a certain size that will not feed a small or stock engine so well. There simply to large for a great idle and excellent response on a engine that is not up to par.

The small primary carb of the triple threat is small for great throttle response and the vacuum secondaries will open as much as needed. It almos sounds like I'm talking about a TQ carb now don't it? LOL

IIRC there is a slight difference for the big block carbs for the 6 pack.
