How Could I Be So Stupid/Careless?

2 brothers story I knew back when. Short, 2 brothers in their teen's got into a fight.
Older brother had a 68 340 Dart. Younger brother lost the fight,in anger (when older brother wasn't around)
grabbed a hand full of 1/4'' nuts,removed air cleaner,opened throttle blades,dumped them in.
Next thing I heard the older brother was installing a 318...
