As noted above, the dual jet is exactly the same as the front half of a CCC Qjet. The Qjet secondaries operate without the computer. If you really want to do this, get a correct 4bbl intake for your 231. Using it with an adapter is a complete waste of time. Also as others have noted, be SURE the problem is with the carb. Few people take the time to really understand the CCC system, and something as simple as a leaking vacuum line or mis-adjusted carb can cause significant driveability problems. Also look to things that are not computer controlled, like the A.I.R. system, which can go bad and pump fresh air at the O2 sensor in closed loop mode, which then triggers the carb to run full rich. The CCC system runs very well when adjusted properly, but few have the patience to do that.
