Clearly I got no dog in this but I personally think the air cleaner vs velocity stacks question, cosmetically is a win for air cleaners. The racer in me prefers velocity stacks but artistically the air cleaners look better as they conform with the overall shape of the motor. The VL stacks look bolted on and the cleaners look like they are part of it. But I mean seriously, it is a 426. You could put two watermelons on there and it is still way cool!
