We are not necessarly talking favorite engine, we are talking favorite photo of an engine (or engines in my case). Try to make it a full frame photo of JUST the engine if you can, that is what this is all about.
I have no idea what sparked me to start this thread but I thought it may be fun and the first "Motor" that popped into my head was the Sissell twin engine Chevy six rail. I saw this car at an event and honestly I was suppose to leave, I had somewhere to be but I HAD to hang around to see this car run. It is a friggin work of art!
