Im running 355, World Heads, solid lifter cam and wet exhaust on my 16 foot Jersey Skiff. We can turn 7000 no problem, and the mid range creates awesome acceleration. I was thinking of going to bigger carb but would hate to lose the midrange.
properly built and tuned a bigger carb will NEVER cause a loss of power in the mid range or even off idle.
That old wives tale comes from people who can't build and tune carbs.
