The bigger carb from the k341 will bolt right onto the k301 & operate good but when the rpms pull against the governor, the throttle butterfly doesn't open much & it does hurt the overall power. The carb opens up just a bit to reach proper rpm even under load while the smaller carb will open up all the way & produce more & better power under load.
I've seen guys in the pulling sport try it over & over again oversizing the carb for the cubic inch it's on & it never works out on a goverened rpm class.
