The Holley Dominator 1150 (PN 0-80673) carburetor was used right out of the box, except for the installation of jet extenders. Jet extenders keep fuel around the jets in drag racing and hard acceleration. Jet sizing will be determined during this engine's first jet check at the dyno. Marvin has also opted for a Holley mechanical fuel pump (PN 12-460-11, 110 gph) to feed this hungry atomizer. The 1-inch Wilson CNC carburetor spacer (PN 024110) is designed to increase velocity, resulting in horsepower and torque increases. Next month, we'll be back with the assembly of this monster engine.
