Hmmmm,,,, gotta be pretty straight forward, you need a slightly bigger hole.
Not being funny (all though I am,
)
I'm running 2X4 Holleys with the Stellings and they fit "tight", but they clear. Mine is a high riser intake, the carbs stick through the hood and up into the air scoop, where the "just" clear there as well.
...alloy lined hood? Nice!
