The balance of our assembly included the excellent Indy 440-2D dual-plane intake manifold, ported and prepped in a previous issue to flow 360-plus-cfm. We will top the intake with a large Demon carburetor. Needless to say, we are going out on a limb with this unusual combination of large, high-flowing heads, combined with a very short duration, high-lift cam, and a large two-plane intake capped with a big four-barrel. The goal is an exceptionally good idle and strong torque, with impressive power into the lower 6,000-rpm range. We expect to put the theory to the test in a full dyno session in an upcoming issue. We'll sample several capacities of Demon carbs from Westech's inventory of dyno carburetors, and hope to experiment with an Indy single-plane intake, to see how the power at higher engine speeds responds. Will it work? We sure hope so, but you can bet we'll be packing a big solid roller stick as a back up, just in case we turn out to be all wet with our experiment. Hey, but it just may work. Stay tuned.
