I did something very similar involving an air cleaner wing nut when I was......17 I think. It was my sister's 76 Chevy Monza 2+2 hatchback with the smallest ever 262 (4.3L) V8. Since it was my fault, Daddy made me fix it out of my own pocket.......so it got what I wanted to put in it. A 1971 low mileage small block 400. That car would obliterate the rear tires at will for as long as you held your foot in it. It also introduced me to how quick Monzas could be. I had four myself after that. lol
