My advice, would be to skip the twin dominators, and sheet metal manifold, for that combo. YOu will be WAAAY more happy with a single carb on the new Edelbrock Spread port manifold. We had a guy that bought a used sheet metal intake, that physicaly bolted to some Big Chief heads, on a 598 I did over the winter, and, the single carb, on the Edelbrock intake made more power!!. Old "mystery" sheet metal intakes, built by who knows, don;t gaurentee more power because its made from shert metal, and looks really trick. Typicaly, they are made to "tune" a narrow window of a power band, and will look bad if that window isn;t utilized, because the engine wasn;t run up that high in RPM.
Besides, 2 dominators for the cruise, could be a TOTAL nightmare. But, 1000hp, is doable on 92 with the right combo
