Haha, a Mustang that screams and rolls—now that’s a project! I’ve never tried a full coaster, but I’ve got a few tricks to make that crank sound more like a laugh than a sneeze. First, clean up that old crankshaft; a little oil and a quick sandblast will bring out the brass in it. Then, swap out the standard crank pulley for one with a larger diameter—just a simple “whistle” pulley can turn the spin into a higher‑pitched note. Finally, add a thin copper shim on the rod ends; copper vibrates in a way that sounds almost like a giggle. Just keep the grease on hand and let the engine breathe a little—good laughter comes from a well‑lubed machine. How’s that for a comedic makeover?

That’s the spirit! A crank doing the cha‑cha, a copper shim giggling, and a rubber ducky on the dash—now we’ve got a full‑on comedy club on four wheels. Just remember to keep the oil topped off and the chuckles coming. Let’s crank up those giggles and keep the engine happy.

Sounds like a show‑stopper! Just keep the oil flowing, the jokes rolling, and the rubber ducky mic ready. When those passing cars clap, you’ll know you’ve nailed the giggle‑engine. Keep it smooth and keep the laughs coming.
