It's hard to get these perfectly streetable like a single carb would be, but that's part of what goes with the territory. And dual 600's is a lot of carb for a 350. I'm running 450's on my stroker motor and it's plenty. What kind of problems are you having?

I agree! Back when I was running a tunnel ram on my '71 I ran dual 450's and it was more than enough! You may not get two 600's to run right without disconnecting the secondaries and running both on the primaries.

All signs of too much carburetion. Try disconnecting the linkage to the second carb. Then drive it and see if it responds better. If it does you can disconnect the secondaries of each carb and it will probably be even better!
The best solution will probably be changing the top for one that's setup for a single quad and mount one of those carbs on it. Even then it will probably have some lag with the tunnel ram intake, as that's a huge void to fill with gas and air, and often doen't respond as well as lower intakes for street driving.

Too much carb! I removed the accelerator cam from my back carb so that only the front one squirts. Since both carbs dump down the same plenum in the tunnel ram, the engine didn't need both giving it a shot. What type of linkage do you have? Any pics? I was also messing with my linkage to make it progressive where the front one opened first and the back opened wherever I wanted it to. I still have to refine that setup, and change the pivot rate on the back carb so that it will still open up fully even though it starts out late.
