Three Rochesters would be ok because you are normally going to be running on the center 2 barrel until you kick it down. Strombergs would be a better cfm match IMO, but they are a little more finicky. Rochesters are just one of those carbs you bolt on and run with.

I'm wrestling with the same dilema, I want the looks of trips on my T, but the darned four barrel runs so good on it and gets such good milage that I hate to upset the applecart. I know I am going to bend and do it though, they just look so good.

Gastrick on here is going through this swap right now and might be able to tell you more about what issues he ran into. He bought a very nice setup at Daytona and is getting it installed as we speak.
