just like the title says? my car is an original 1968 350 2bbl. car and i want to put in a 400 ci. into it. i remember hearing that there is more parts availabilty for the 400's. i know that the 69's have a different water pump set-up but what else is different? so guys which one should i start looking for and trying to get? is one better than the other? or will it not make a difference? Hey Quenton i will send you an PM later on some big question that i have! thanks in advance.
