Go with the 225 carbs as they WILL get you better economy. The 200's will give better throttle response, but don't get as good of milage. Just make sure they are actually 225 mid bores as there are about 4 or 5 different venturi sizes for the plastic carbs. The V-6's used 2 main sizes of carbs, the 200 small bore and 225 mid bores. There was also the infamous 200's early on that came on the 200GT's that were MONSTERS of carbs, but they are not good for much but WOT. Then there are the V-4 carbs which there were some that were almost identical to the V-6 ones, but would be a 1/16 or so smaller or larger than the 225's. vSO make sure all of the venturi's are the same size. And don't mix and match baseplates as the yare calibrated for the carb bodies for air bypass and jetting for idle and mid pull-offs.
