I've run snipers on both dual and single plane intakes with 600+ HP combos and to be honest they function fine on either. I had no tuning issues at all.

I let the engine combo decide what intake is best, not necessarily the fuel mixer since it's still a wet flow setup.

With a 500ci Pontiac, if you aren't trying to look stock, I wouldn't even think of putting a dual plane on it. It'll make so much friggin torque down low anyway you don't need to try to enhance that part with a dual plane. I'd do a single plane and never look back.
