With that engine, I would suggest an RPM air gap. Car Craft and Hot Rod both have done tests comparing low duals, high singles, and high duals like the air gap and have shown that the RPM air gap really is the best of both worlds... only drops a couple hp on top and still maintains the torque down low.

If you had a 383 that can use the extra air, or more heads that would take advantage of the top end breathing, or a race-only setup, I'd suggest maybe a single, but it takes a lot of engine to need more than an RPM air gap.
