Quadra-Jet
Hey, it’s starting to look like a carb again. The throttle linkage has been assembled using replated hardware and the throttle plates have been screwed to the replated shafts (red Loctite was dabbed on each screw before tightening). Notice the tapered edges on the secondary-circuit throttle blades, which create a positive seal to close off the throttle bores. Sean didn’t fully tighten the blades to the shaft until they were adjusted so no gaps were visible in the closed position. Here Sean is showing the proper adjustment for the WOT throttle-blade angle. The primary-circuit throttle blades are perpendicular to the baseplate, but the secondary-circuit throttle blades are slightly angled. This angle is necessary to keep the airflow as laminar as possible (not turbulent) for a straight shot into the intake plenum. View Related Article
