Almost a perfect engine, the only thing thats disturb the picture is the Battery and radiatorhose.
The engine in my own New Yorker, it's a little customized with extra chrome and stuff. Will be restored back to original in a near future.
This is how a engine can look like if you can find it in a salvage.
