Engine point straight back?

[WSSix]

I'm kind of embarrassed that I don't know this off the top of my head and that I didn't noticed when I did my swap. My engine doesn't appear to point straight back down the car. I know it's offset to the passenger side like it should be. Should it also point straight back?

My subframe is square. I double checked that before I did the connectors. All I did when I put my engine in was drop it in place and flip the transmission mount pad upside down. I'm fairly certain I didn't change it's location side to side but that was four years ago now so maybe my memory is fuzzy. Since looks can be deceiving, how can I verify if it is pointed straight back or not? Plum bob the crank pulley and drive shaft yoke and verify offset measuring between the frame rails?

Thanks
