I was toolin around the internet looking for replica 1/10 scale engines and came across these beauties. And get this, they all start and run!! There's even a v-twin that they will install in a scale Harley. I've heard these things start up and the sound is truly incredible. I also saw the Ford panhead V8 shown below installed into a 1/8? scale A/C Cobra, it even had a 4 speed transmission and side pipes.

 

I saw a small 1/5 scale ferrari v12 motor once that ran. I will have to dig up the video, it took the guy like 2 years to machine, apparently it;s in the ferrari museum right now.

 

I saw that video too, that was awesome!!! It still sounded like a ferrari too

 

I thought it was something closer to 10 years?

 

here's a 1/3 scale full car...
