Carburetor selection will play a MAJOR role here. Two of the Edelbrock Thunder Series Carburetors with easy-to-adjust Secondary Air Valves (only requires a small screwdriver!) would be a great choice here in the 500 CFM, or maybe even the 625 CFM size. Both Edelbrock and Weiand make oval port Tunnel Rams with slightly downsized runners and smaller plenums designed with street use in mind. Don't forget that Edelbrock recently released a Dual Quad Air Gap with part #'s for either oval or rectangular port Rat Motors. I've actually purchased one of these intakes for my own ride because I'm a huge fan of the mid-range torque that a dual plane manifold provides. Now I've had some fast stuff but for whatever reason I skipped my "tunnel ram phase" in my younger years but I'm gonna make up for it now. As tall as it is, I'm gonna add a little more height to it with 1-inch tall, 4-hole carb spacers and probably the K&N Velocity Stacks that utilize filters. I also plan to grind off the "Edelbrock" script and do a few little tricks to make the intake looke a little more vintage. These Dual Quad Air Gaps are actually very reminiscent of the very tall Z-11 intake that came on the factory Drag cars of 1963.
