I've seen stroker kit's for the ecotec v6 that change the capacity to 4.2L, but i cant find any for the buick motor. Are there readily available kits for the buick motor anywhere or are they hard to find.
beat me to it! yeah man they come in 4.3 kits for the ol buick i have one sitting at prostroke still was gonna put it in a boat but i need a boat to put it in
