I got a question. i am a rookie at this, but i already know that i can take my 3.8 liter v-6 out and put in a buick 350 no problem. the question i have is that will my radiator i have work, because i just replaced it and i dont want it to be a waste of money for this swap. also, will the orginal down pipe and cat work with the 350. i just put on a dual outlet single inlet flowmaster on, and i dont want that to be another waste of money. thank you very much for you time. the always curious, danny
