I just finished a pair for a customer on a flatie.
Read the hamb board holley 94 page and seen all the suggestions. After a couple trys , i blocked off one carb and synced the throttle plate to a number ( i think it was a 8 on my sync tool) removed and then ran the other carb and adjusted as a single to the same number. Wasnt exactly right even still. Removed both carbs and installed power valve block offs and it was perfect. Talked to the guy last night and the car has been great ever since.
Another problem i noticed while doing this car was the manifold vac dropped 2 inches with the two carbs versus one carb, just something else to consider.....
