The Carter 320D2GC / 320GX C4.4 Electronic Fuel Injection Engine
In a forgotten construction site, buried under dust and silence, lay a broken machine —
a Carter 320D2GC 320GX C4.4 Electronic Fuel Injection Engine.
Once it roared with purpose. Now it slumbered in rust.
But deep within its steel heart, a spark still lived.
Not a spark of electricity—
but of consciousness.
When the Carter C4.4 Engine Reincarnated as a Dragon’s Heart!
🧠 Prologue:
Once upon a time, I was just a hardworking Carter 320D2GC 320GX C4.4 Electronic Fuel Injection Engine — loyal, powerful, and proud to push dirt for a living.
My days were simple: start, roar, dig, stop.
Until one day… a thunderbolt struck me straight through the fuel line.
When I opened my sensors again —
I wasn’t in an excavator anymore.
I was inside... a giant dragon.

It was quiet, yet possessed a power poised for unleashing; it was stable, yet concealed a surging passion.
Just like you when we first met, your eyes were gentle, yet concealed a firmness I couldn't fathom.
