You're going to get support on both sides here so I'll start. If it were mine I would be looking at one of the new self-learning EFI units that bolts on like a carb. MSD's new Atomic unit looks to be an all inclusive, compact package with only a few wires to hook up. FAST's EZ EFI is another, and Holley has one, too. I'm running the Edelbrock ProFlow XT, and as one of the first SBF packages out it was not self learn but it can be converted with the addition of a wide band O2 sensor and uploading a different firmware package, a two minute process. There're lots of other packages out there, with wide range of pricing.

The beauty of the EFI is that you can change your Air/Fuel map in easy stages, if you go into the self program mode, where with carbs you're going to be pulling it apart to re-jet primaries & secondaries chasing the "ideal mix". Also, with a ECU controlled distributor, timing changes are the same simple map change. I love the flexibility of tuning with EFI.
