While working on my 383, with Holley 4160 750 CFM carb, I was trying to remove a nut off a bolt on the throttle arm. I think I heard and saw a washer fall off the bolt and vanish somewhere between the intake manifold and the engine head. After researching the intake manifold to find out what kind it is, it appears to be a Mopar Performance M1 Dual Plane Aluminum intake that has been painted orange.
There is a U-shaped opening in the head directly beneath the edge of the intake manifold. The opening looks like the bottom of the letter U. I think perhaps the metal washer fell down inside this U-shaped cavity. What is this opening for? If something falls down inside there, could it somehow find its way inside the engine and cause DAMAGE?
I started messing around with the throttle because I had the return spring fly off the throttle arm and shoot across the engine compartment. Was then trying to determine why it flew off, when I found some poorly done work on securing the linkages, including the use of a rusty bent nail (instead of a cotter pin) to hold the throttle linkage to the arm.
