One piece motor??
 

I have a bet with a buddy that their is a motor out there that the heads and block are one piece. Has anyone ever heard of this or seen one?

If we're talking about any motor at all go look at your 2 stroke weedeater.

We are talking about car engines.

Flathead engines.

rotary has no heads....

i remember it being like a v8. Not a flat head it was more of a modern motor.

google?

I have never heard of such a motor... wouldn't be practical as you could not do any repair work.
