    What should I do

    I am building a motor for my 400. This is the list. 416 12.5 compression,Curtis sparks cam,Curtis sparks exhaust. Should I put-on my 06 450 carb. Or should I leave the stock one on. And what should be the tune. Thanx

    Do the 450r carb. Its a fool proof setup and is super easy to do!! It is the best bolt on mod for the Ex i've ever done.
